Part I: Why should I do this?
Why digital preservation?
Believe it or not you or your family’s, or your organization’s history is unique and
preserving at least some of it in a digital, more easily accessible format, is one
longtime gift you can make to your family, your organization, and your community.
Actually most professional librarians and archivists, and digital media specialists, will readily tell you that
digital media (hard drives, flash drives, cds and dvds) are not a preservation medium. Their basic point
being that the electronic bits and bytes used to reproduce and save digital copies of historical materials
is stored on digital media that will not last over time, especially when compared to the “old” media like
paper or even microfilm.
Trying to save valuable personal or family archival material (documents, letters, printed items,
photographs, etc.) by digitizing them with a scanner or a camera can still be a way to preserve them, and
it will definitely make them potentially more accessible to family, friends, and the wider community if
you are interested in that (we are!), but this process by itself is not a long-term preservation medium.
It is true, however, that once an item has been digitized it can readily and easily be recopied time and
time again to the next storage medium. In fact, this is a necessary activity for any items you digitize that
you hope to make available for a very long time. Because if you wait too many years, the original disc or
drive may have deteriorated such that nothing remains on the media to view, or, it will be stored on
what has become a very old technology and thus difficult if not impossible to copy over to an up-to-date
device.
So, if the above is true, why would we create a best practices manual to show you how to “preserve”
your historical materials in the location where you live or work?
Well, we think there are lots of good reasons:
1. You just never know when the dogs are going to eat your
homework or priced possessions!
2. Your own history is important not only to you but, more
than you probably realize, to others as well.
3. The chances of your original material being permanently
preserved in a professional, well run library or archival
credit
2
institution is probably not that great.1
4. Capturing at least some of your archival history by digitizing it is better than saving none of it
(see 1 above).
5. You might not think that your own life or history is important but, believe us (because we have
seen it time and time again), your children, grandchildren and lots of people in your community
will.
Can a local institution help me?
The chances are that you have a local institution who might be able to assist you in some way, whether
it is just giving you advice on how to take care of your personal or organizational treasures, or even just
whether the material you have has historical value to the wider world. Our guess would be, yes. Here in
Greensboro, N.C. there are numerous libraries, archives, and even museums, who are available to help,
as can be seen in Appendix 1. In fact, this best practices manual is actually the result of the efforts of
the Digital Projects Unit of The University of North Carolina at Greensboro University Libraries, whose
mission includes helping to preserve not only the history of the university but also engaging the wider
community by helping to preserve and save, often by partnering with local institutions, the city’s
valuable, diverse history.2
Can you show me an example of what you are talking about?
The Digital Projects Unit recently partnered on a grant with College Place United Methodist Church
(Preserving Local History: A Field-Based Digitization Pilot Project) to test concepts and procedures for
taking digital cameras into the field to capture some of their yet-to-be digitized historical materials.
What we learned from this project forms the basis of this best practices manual, and also the beginning
of our Community Collections website.
The process we undertook can, we believe, be replicated by you or a small group of people in your
organization, or at home. Here is a brief outline of the steps involved:
1 We are in fact huge advocates of donating historical material to your local institutions, or to universities or
colleges or any other institution with whom you have a connection and who collect historical materials; we would
certainly encourage you to pursue those opportunities if they exist. But, in reality, much of the history we create
as individuals or groups will probably not find a permanent home beyond the walls that currently contain it. The
other thing to keep in mind is that these local or regional archives and libraries, even if they are not interested in
acquiring some of your materials, are very happy to give you advice about the best ways to help protect your
originals. See Appendix 1 below for local contacts and resources. 2 For more information about the Digital Projects Unit see: http://libcdm1.uncg.edu/cdm/ and
http://library.uncg.edu/dp/
3
1. Discuss with your family or your organization what is important and worth digitizing.
2. Select which of these items to digitize.
3. Select your equipment (our step by step information in this manual will show you how).
4. Document what you shoot on the initial camera frame & in other documents (paper, word processing program) where you give a brief initial description of the item, e.g. “Church register, membership, baptisms, 1914+”.
5. The most important thing to do … spend lots of upfront time setting up/stabilizing the equipment. You will learn in this document about good, low cost ways to do this.
4
6. Now, the fun part … photograph lots of items in a relatively short amount of time! OK, there is significant time required afterward to prepare your files, but nothing of value or worth doing comes easily.
7. Save the scans on at least two separate digital media (cds, flash drives, computer hard drives, etc.) and keep them in separate locations. - Upload the material to your own website, your organization’s website, or, better yet, with a local institution or local/regional web portal. We provided this for CPUMC, and a couple of other local organizations (and will continue to do this in the future) through our Community Collections website.

Part II: What should I digitize?
How do I choose what to preserve?
The online survey we conducted as part of Preserving Local History: A Field-Base Digitization Project
showed that the most popular items that local groups and organizations would choose to digitize if they
could were, in this order:
1. Photographs
2. Correspondence
3. Pamphlets (small printed items, like capsule histories, etc.)
4. Deeds/Marriage certificates (there were numerous churches who participated)
5. Artifacts (three-dimensional objects)
6. Architectural plans
What are some of the things I should think about when deciding what to
digitize?
The best items to start with are usually those that are important to you, or your
organization.
● Are there things that you would like to access more easily?
● Are there diaries or meeting minutes, or really cool/interesting graphics and photographs that
you often look at or remember?
Is there a big upcoming event, like a milestone birthday, significant anniversary,
or even a wedding or big event?
● Look ahead and think about such events in coming months or years.
● This would be a good opportunity to digitize some of this old memorabilia to use in a slide show,
or put on a poster or an invitation.
● Once you digitize it, and use it in an event of some type, it can become a great promotional tool
for doing even more.3
3 One decision our project made was to choose at least a few items that had visual appeal. We chose photographs, some interesting scrapbooks, and even some architectural plans/elevations from College Place Methodist Church (which were a real challenge) to include in our Community Collections website.
6
Do you need to impress someone in your organization?
● If you need your boss’s or the organization’s board support (or maybe just your wife’s or
husband’s!) in order to get some funding to take care of or digitize your historical materials,
then think about copying/digitizing items that might be of interest to them in some way.
● How about digitizing their portraits! OK, it doesn’t have to be quite that obvious.
● Still, instead of those “interesting” quarterly reports or other (potentially) important but less
exciting items which you have been dying to digitize for years, maybe think about starting with
some interesting photographs or old posters, or important documents that might grab people’s
attention.
● Again, look ahead to what is on an upcoming agenda in the next six months or a year
(organizational or family) that could be enhanced by including some historical components to it.
Do you have in your possession some really interesting items that might be relevant? Digitize
some of those and make them available well in advance, and then promote them to the
organizers.
● Of course the ideal situation is for people to already know some of the treasures you have and
come to you to ask about getting digital versions. But, hey, sometimes you need to be proactive
and prepared for launch!
Of course you may also have many items that may be in very poor condition,
difficult even to hold or to turn a page.
● If particularly valuable either historically (to you, or your organization) and perhaps even
monetarily valuable, you might very well need to reach out to professionals to handle the
digitization.
● But many personal/family/organizational items can still be handled, even though they may be in
poor condition. You might think about working with and digitizing these items first.
7
Part III: What equipment do I need?
Okay, so what are some of the tools I need to get started?
For our project, we tested several cameras, experimented with several ways to create a low cost
portable platform (or copy board/stand), and searched for inexpensive ways to help stabilize the items
on the copy stand if they did not want to stay flat on the board.4 This is what we found:
A. Cameras
Here are the four cameras we tested. The iPhone was a last minute decision, and was not used
extensively, but rather we wanted to see how this fairly widely available/used camera would compare to
3 the three main, dedicated cameras we used.
$100 $650 $1100
1. Grid Screens
A screen with a grid pattern on it was available on all of these camera’s displays and, as we note below
in Part IV, this is a very important feature to have because it helps to “square” up the image. The
advantage? If everything is squared/leveled/parallel at the start, the images will be much easier to
straighten and crop (if necessary at all) and prepare for their future use (on the web, in a publication,
etc.)
Item that is pretty square/level
Item that is not square/level
4 The Fopydo portable copy stand came to our attention late and we did not test it. However the reviews look promising and at $30 we will probably test it in the future. http://fopydo.com/
8
2. Sensor Sizes
In general a camera with a bigger sensor size (see below) -- i.e. the “film” section of the camera where
the digital image file is captured -- will have better resolution, and less digital “noise” (see below)
Sensor size is different than the “megapixels” that are usually touted as a selling feature. In general, point and shoot cameras, and phone cameras have very small sensors (because the devices are small!), whereas bigger cameras (like DSLR’s, i.e. Nikon D7000 & the Sony above) have bigger sensors. Sensor size comparisons (below shows the relative, not actual, sizes):
Digital noise:
But, as you will see under Part IV (steps 1-4), basic techniques are just as important as the camera you
use. So, don’t let the fact that you might not have an expensive, “professional” level camera keep you
from photographing your historical materials.
9
3. Focusing
All of our cameras had automatic focusing, but the Sony and Nikon also had manual focusing. The Sony’s
was more difficult to engage, so we did not use that in our tests. We did use the Nikon DSLR’s (Digital
Single Lens Reflex) manual focus a lot, since it is easy to engage, and you can see the item/focus on the
screen easily.
The advantage to manual focus?
● Once you have your copy stand/camera/
tripod “locked down”, with the item to be
copied all set up and in sharp focus, the
camera will hold that focus as you turn the
pages (unless you accidently hit/turn the
lens barrel).
● Also, auto focus modes on digital cameras
can often “hunt around” for the perfect
focus, which can be pretty annoying and
frustrating, which is when manual focus can
really be handy to have.
The disadvantage?
● You have to remember that the camera is in manual mode, because if you change items on the
stand, and do not refocus when you put the next item on it, the images may no longer be sharp.
Our advice:
● For most people it makes sense to use automatic focus, but just be sure you check the image
sharpness when you are setting up, and periodically as you go along.
● If you know your camera well, and it has manual focus, and if you run into a situation where the
camera is “hunting around” trying to find proper focus, then certainly use the manual mode.
4. Exposure, F-Stop and depth of field
Using the camera’s automatic exposure is normally sufficient to get good exposure, so try that first.
Also, it is very possible that your camera will not have any manual modes at all. However, if it does,
keep the following in mind:
If the camera has an “Aperture Priority” mode -- also known as, or appears as, “A”, or “AV” (aperture
value) -- then take it off of automatic, and engage this mode.
A note about manual focus on a DSLR:
It is easy to engage most DSLR’s (see this image
from a Nikon), from Auto Focus to Manual.
Once in manual mode, it
is easy to focus the lens
by turning it, plus, you
can see easily the result
either in the eyepiece
viewfinder, or on the
actual screen in most
recent models, right away.
10
Why? Your camera will be on a tripod, so a fast shutter speed (also known as shutter priority, or “S”, or
“TV”, for timer value”) is not as important. An automatic, or a shutter priority setting could change the
exposure appearance. An aperture priority setting will generally not vary as much, since the aperture
opening stays the same and only the shutter speed changes. On the other hand, a shutter priority
setting means you have a constant shutter speed, but the aperture size/opening will vary, which can
sometimes cause some issues.
The “F-Stop” of the camera (which will probably be set automatically in most camera, except for DSLR’s
(“Digital Single Lens Reflex, like our Nikon D7000, or advanced point and shoots) is important to be
aware of, if your camera (or your knowledge/skill) allow you to control it. If you can control the
aperture, use an f-stop that is not too large (e.g. like f1.8 or f2.8, in example A below), since this will
cause a very shallow depth of field, where the plane of focus is very narrow. See an explanation of
exposure and focal lengths here.
THE BOTTOM LINE: If you can control it, it’s better to have an f-stop setting of around f5.6 or f8-11,
where an item will have a wider plane of focus, as seen in example B below, as opposed to example A,
which probably had a setting of f2.0 or lower. BUT, don’t stress if you cannot control for that, rather,
just check your particular camera set up and the images it is producing and make certain they are in
focus.
For more information about camera exposure, see this wiki website.
Lens with a large aperture/opening, and shallow depth of field (e.g. f1.8)
Lens with a small aperture/opening, and a wider depth of field (e.g. f8-11)
B. Tripods
This is a vital, essential piece of equipment. It is impossible to hand hold a camera and get as sharp an image as you can using a tripod. So, plan on that expense if you don’t have one. Or, see if a friend or colleague already has a tripod that you can borrow and try out. That's what we did for the project.
11
The good:
● The right price (team member loan)! ● It was sturdy, light-weight aluminum
Not as good:
● It was difficult at times to get close to the table, so the item would be fully in the frame, which will be true of most tripods without an extension (see below).
● There were issues with shadows from tripod legs, in some lighting situations. Solutions:
● Straddling the table or copy/platform, in some fashion as seen above, was one approach we found that worked for our tripod.
● Whatever your solution, once you find it, “lock” everything down with duct tape so nothing moves.
Are you buying a new tripod? If so, consider buying one, whether new or old, with an extension arm, or the capability of adding one, like those pictured here at right. This will solve the issue of not being able to get close enough to the copy platform/stand, and also any problems you may have with the legs casting shadows on an item. You can also buy just an extension arm for an existing tripod too, e.g. those made by Photek.
12
C. Copy Platforms & Stands
Since our project was designed to explore the use of lightweight, portable approaches to copying
historical material, we chose to use various non-traditional, relatively inexpensive materials that we
could take into the field with little difficulty.
We used a magnetic dry erase board, green grid cutting mat, and wedge sleeping pillow, as follows: 1. Dry Erase Board:
● Works well with thin magnetic strips that can hold corners down. ● Had small grind printed on it, but was impossible to see in a camera screen, so we used a piece of
blue graph paper, on which we highlighted the lines in black, which made them easy to see. ● If you have the board titled at a 45 degree angle, which is good for setting up the camera, items
have a tendency to slip down the board. We were able to adhere bigger magnetics at the bottom which would keep items in place.
● Many items open well & lay flat (on all surfaces) which makes the copying process go very quickly.
2. Mat-Cutting Board (self-healing):
13
● The grid board was very easy to see on the camera screen, the surface was not slippery (like the magnetic board).
● It does require, however, that it be placed on a table, or board, because the grid board itself is very “floppy.”
3. Wedge sleeping pillow:
This might be the best solution we tested:
● It is lightweight & can take long push pins being inserted into it, to stabilize items. ● The pillow case fabric (even with the grid fabric on we placed on it, at right) is very “tacky”, and
the wedge is an ideal angle for tripod/camera. ● It was necessary to find a way to make the wedge pillow case more visible, and we found pre-
printed grid fabric that we could adhere to the surface (with Velcro; you could just tack the corners & middle with thread too).
4. Copy stands (traditional):
We did not use a traditional copy stand since they are generally not portable. However, we are certainly
not opposed to using them. Here is a link to some excellent information about their use with cameras.
14
Advantage?
● It is a stable platform, and everything is square/aligned, and if there are lights attached, or the
possibility to attach lights, even better since one can get even illumination of the items.
Disadvantages?
● It will probably be too heavy to carry around, and there may be items that are too big to put on
the baseboard so the camera will not be able to capture it in one image.
Our Advice?
● If you are an individual with a lot of material to copy, or an organization anticipating a lot of
material to digitize -- and will be doing the work in one location, not moving around like we were
-- if you can get access to a traditional copy stand (even if used, or a loaner) we would highly
recommend it.
D. Stabilizing Devices: How to keep items flat?
We tried various methods to keep items flat, so that they would stay in the “plane of focus” near the
surface of the copy boards.
1. Piece of Glass:
We had some success with using a piece of
glass (pulled from an unused 11x14 inch
photo frame, which we taped around the
edges to protect our hands from getting cut).
This can work very well, but only for single
page items (a letter, or photograph, etc.), or
very thin pamphlets or brochures, which
pages are not bulky. So, it might not work for
every situation/item, and there is also the
issue of carrying it with you with the chance
of breaking, etc. (so, if you do, probably put it
in a cardboard protected sleeve.)
15
2. Magnetic strips, pointers, even fingers:
We had various degrees of success with these methods, the biggest drawback being that they will
usually be seen in the final digitized image.
● Magnetic strips will probably be visible in the image (see at left below), but can be found and cut
to whatever size you might need. For example see here (or do a web or Amazon search under
“magnetic tape”)
● Pointers, if they are long enough (e.g. middle below was too short, but one on the right was
better) they will probably not be as noticeable.
● Telescoping Pointers: We did not use these, but they could be an inexpensive approach,
especially if you take apart some old TV rabbit ears In addition, since they can expand to a
couple of feet or more, one person could possibly hold two of them, placing one on opposite
sides of an item.
E. Computer software
Since this entire process is digital, you will definitely need some computer software in order to process
and finalize the digital files you have taken. The basic functions required of the software are:
1. Ability to rename the files, from the initial title given by the camera, e.g. _DSC4631.jpg, to
something short but descriptive, e.g. photo 001.jpg, or postcard 001.jpg
2. Ability to crop the images (individually, or as a group). If the images you take have wide borders
around them, or if the borders are not pretty consistent in size, then you will need to crop them.
16
That is a good reason to set up the camera and item as carefully as you can in the very
beginning, so the image you capture will not need much manipulation/editing.
Here are examples of free, or low cost software that you could use. But, as always, if you are already
using something that you are familiar with, which can do these basic edits, then use it. Also, check to
see if there is an existing program on your computer that you have never used,.
● Picasa (free) http://picasa.google.com/
● Gimp (free) http://www.gimp.org
● Fotor (free, online) http://www.fotor.com/ (and see this video)
● Photoshop Elements ($99 or less) http://goo.gl/tfw8al
Can't I just use a flatbed scanner and not worry about all these issues?
Our project was designed to test portable, affordable, easy to set-up equipment, which we hope to use in the future for digitizing local historical materials in homes, businesses and organizations. But to answer your question, yes, of course you can use a scanner. In fact, a scanner and computer might be your best solution, especially if you have a dedicated space to set them up. And it’s possible your organization already has an office scanner/printer that could work. Advantages to using scanners:
● The quality can be much better, if you use the best settings available. ● No need to worry about lighting, items being flat and out of line/square (it can still be an issue
for bound volumes, see below, but for single items, or small pamphlets, not so much)
Disadvantages:
● More complicated items (bound volumes of any type) have to be turned upside down, and you cannot see how they align until you do a scan.
● Bound items in poor condition can be further harmed, and items can even fall out when you turn the volume upside down.
● Although quality is better it takes a lot longer to do a scan. In our camera tests of two items (shot by 4 cameras, and scanned with our Epson XL10000 scanner) the shortest time to digitize the same item was 10-13 minutes with the cameras, compared to 32-39 minutes for the Epson scanner.
● Scanners have a fixed size glass size, so larger items cannot be scanned in one pass and may have to be scanned in several parts, whereas a camera normally has a zoom lens, which will allow you to adjust the frame to capture the entire page.
There are excellent resources and information on the web about using scanners to digitize materials, here is one example (see especially chapters 2 & 3.)
17
Part IV: Quick set-up procedures
1. Find a suitable place to put your copy platform/board
● Best location is a window with natural light and no sun, giving even illumination.
● If there is only overhead light, try to position copy board to avoid glare as much as possible.
● If you are setting up in a semi-permanent location (at home, or organization) having two lights
(on stands, or clipped on, at each side, at a rough 45 degree angle) would be ideal, e.g.
Even northern light illumination
Artificial light at 45 degree angles
A note about color balance:
Most cameras are set on “auto white balance,” which means that it senses/measures the color of
the light, and adjusts the balance accordingly. It is probably best to keep it on that setting, but if
the initial images seem a bit off, and you know how to check/change the setting, certainly consider
manually adjusting your camera's white balance. Check out this helpful wiki.
2. Attach your camera to the tripod
Position it close to the copy platform/board. The tripod may need to straddle a table to get close
enough, permitting the proper angle/alignment of camera & board.
3. Line up screen grid with platform grid,
Look through camera eyepiece or its screen, and adjust the camera/tripod mount so the two grids are as
close to parallel/squared as possible; you might not get it perfect, but get as close as you can. This will
make for much easier alignment and cropping in the final, processing phase of your digitization project.
18
4. “Lock Down” the tripod’s feet
If at all possible, do this, and also do it for the copy platform/stand. If you can use duct tape, well that is
an inexpensive solution. But if not that, maybe some type of “sandbag” weight (at least for the legs).
Most Important Are Steps 1-4 Above: If you take your time, and do all of the above procedures, your
chances of getting a very acceptable image -- no matter the camera you are using -- will increase
tremendously. So, be sure to spend this up front time setting up.
5. Place the target on the copy platform/stand
Include at least:
Name of the organization/person (if you have a lot of items to do, just create a word processing
version)
19
Date of the digitization
Name of the item (or, if you are keeping a separate numbered list of items, just the item
number).
6. Place the item to be copied on the copy platform/stand:
Align its edges with the grid squares.
Check that image in the camera eyepiece, or on its screen, fills the screen but allows space all
around.
Note: On many cameras, what you see on the focusing screen might not represent what will
actually be captured, so it is wise to leave some space around all edges of the item. On the other
hand, don’t leave too much space, because you want to use maximum number of pixels that the
camera has, to capture the image, so that you will get the best quality image.
Leaving enough space around sided
Leaving too much space
20
7. Will the item stay flat?
If not, secure it to the copy board/stand using one of the methods as outlined in Part III, D above.
8. Is all the material the same size?
If not, this can be a challenge, so be prepared to
tackle that issue, which can slow down the process
quite a bit.
9. Now the Fun Part
Begin taking photographs!
Consider using the self-timer (if the camera has
one) to prevent camera shake. If your camera does
not have a self-timer, or you do not know how to
engage it, be gentle in pressing the shutter button.
Important:
After you take the first image, check to see:
a. Are all the outer edges of the item visible?
b. Is the image sharp? Use the camera’s enlargement tool to zoom in on the screen to check
sharpness.
c. Is the image fairly well exposed, not too dark and not too light?
d. It is a good idea to check as you go through the items you are shooting, periodically, to see if the
focus and exposure is still good.
Note About Different Size Items:
If an item/group to be digitized has various sizes
included in it, like a folder with lots of items, e.g.
8x10 photos and 4x6 photos, or different size
pamphlet or printed items, and, if you can
determine that there is no particular order, then
you could set up your camera to first digitize all
the items of roughly one size, then change the
zoom lens to capture the other size items.
This would be more efficient than having to
change the zoom range/size every few items
If, however, there is a set sequence to the
material, like in a scrapbook, you will have to
digitize in that order, and adjust the camera as
necessary.
21
Part V: What happens after I take the pictures?
Organizing the digital files
You can make your life much easier by having a plan for organizing and storing your digital files in
advance. You might opt for using the free photo management software that may come with your
computer (e.g. Apple’s iPhoto) or by purchasing something more advanced.
At a minimum, though, you will probably want to create folders that fit the logical arrangement of the
items you’re scanning or photographing. For instance, you might want to have folders containing all the
letters written by one person or all the material related to a certain church event or family reunion. The
worst thing you could do would be just to drop all your digital files into one place with no arrangement
or hierarchy. Think about it; you (or more importantly, someone else) would never be able to find
anything.
You might also want to consider writing a few sentences of text about what a folder contains and saving
that it the same folder as the digital images. Even better (but much more time consuming) would be an
inventory listing each photo and a caption. Microsoft Excel spreadsheets work nicely for creating such an
inventory, and Google Docs is a free, web-based alternative. If you do an inventory, be sure to include
the filename as one column so you know what information goes with which photo!
Sharing the images
Your main goal may simply be to have images available internally for your organization or family
members. If so, then you’ll be fine saving them locally on a computer and maybe on CDs or flash drives
(but see the section on preservation and backups below).
On the other hand, if you want to make them available to a wider audience online, you have several
options, many of which are available with no cost as long as you have an internet connection:
22
● flickr offers considerable free storage space for photos and permits you to decide whether your
images will be avilable to everyone, just you, or to friends and contacts you can set. You can add
captions and tags as well as create albums and groupings of photographs. You do not, however,
really have the option of doing customized web pages that talk about your organization.
● Cloud-based file storage systems such as Dropbox, Apple’s iCloud, and Google Drive also allow
you to store files in a sort of cloud-based extension of your own computer. Many of these sites
also allow you to share files with your friends or the public but, like flickr, not on customized
web pages.
● Free web hosting options, such as Wordpress, Weebly, Wix, or Google Sites, will allow you to set
up an actual website with pages you can more fully control. Many of them have options to
create blogs and photo album pages, and some will allow you to include photos that are stored
on flickr in a more customized way. These options generally require relatively little technology
background to create a basic site and some allow more customization for advanced users.
● Low-cost web hosting options, like Pair or Dreamhost allow you build fully customized websites
but also require that you know how to do this from the ground up.
Many of these options also allow you to permit user tagging and comments, which is a great way to
involve other members of your group (or the public) in describing the images, adding details you might
know, and sharing stories in general.
Long-term storage and backup:
As we state early in this manual, digitization is not considered to be a foolproof method of long-term
preservation. There are things you can do, however, to maximize the viability of your digital images:
Backup early and often:
You cannot have too many backups stored in too many different places. You should have at least THREE
copies of everything stored in THREE DIFFERENT physical locations. Consider keeping one copy at home,
one at your office or someone else’s home, and maybe one in a safe-deposit box or other secure setting-
-in addition to an online or cloud-based backup/website. And remember to update ALL these backups
regularly as your collection grows.
Use stable media:
CDs and DVDs (optical media) that you burn on your home computer are wonderfully convenient ways
to store materials in the short term and to provide other people with copies. However, they are NOT a
safe way to store digital files for a long period of time. Optical media degrades relatively quickly,
particularly the type used with home computers. These disks are also subject to many harmful
23
environmental factors. Despite the additional cost, it’s much better to use multiple magnetic devices
(e.g. internal or external hard drives). You might even consider just saving copies on multiple computers
in different places. Again, consider also using an online or cloud-based option and remember to update
ALL these backups as your collection grows.
Check your backups:
A corrupted backup is no good to anyone. Don’t forget to check your backup media frequently to make
sure they’re still functional and accessible.
Consider partnering with a larger institution:
As we’ve mentioned above, local libraries, historical societies, and others may be interested in obtaining
your materials and handling their long-term storage. At a minimum, archivists and librarians at these
institutions may be able to provide advice. They may also be aware of grant programs and other sources
of funding that could help you in your mission. See contacts in the appendices below.
Here in Digital Projects, we would love to hear from you if you have questions about using cameras to
digitize your historical material, or if you would like advice on what to do with your materials. If we
can't help you, we can put you in touch with someone who can.
