Streams Quick Overview About me Defining discovery for the talk
Agenda Setting the stage Where we are now What are the challenges
Where were going
Slide 4
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams POLL: Please tell us if you use one a web-scale discovery
service in your library: A. EBSCO Discovery Service B. Primo C.
Summon D. WorldCat Discovery Service E. Something else F.
Nothing

Streams SETTING THE STAGE
Slide 6
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams A Brief History Ancient History (the 1980s) Command Lines
Experts only Library equivalent of a 900 area code: pay by the
minute More recently (1990s) Web interfaces Many databases Despite
vendor claims, still experts only Google
Slide 7
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams More Brief History Recent Past (early 2000s) Still more
databases! Federated Search Google Google Scholar Today (2010s) Did
I mention Google? Web-Scale Discovery
Slide 8
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams Illusion of Comprehensiveness There used to be a few online
sources for everything that was online Then, there were multiple
places to go to find much of what was available online Now, there
are a few places to go that have much of everything available. And
many places to go that have small but oh-so-significant pieces of
whats online Illusion of being comprehensive has never been
greater.
Slide 9
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams A Sea Change In the previous eras of discovery, resources
were diffuse in access and concentrated in origin. Web-scale
discovery has flipped that. The resources are diffuse in origin and
concentrated in access
Slide 10
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams HOW WE THINK ABOUT RESEARCH IS CHANGING

Slide 12
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams It Was Not That Structured How to characterize the
information universe We used to have many sources A few things were
in many places Many things were in few places A few flows of
information across the infosphere; information owners were
proprietary about their data.

Slide 14
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams Where Are We Now? Web-scale discovery a few concentrated
sources for some libraries Still many databases Increasing use of
local repositories
Slide 15
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams Oceans of Data
Slide 16
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams MANY CHALLENGES & A FEW SOLUTIONS Or perhaps,
directions toward solutions
Slide 17
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams Is Everything Really Everything Lack of transparency
throughout Is my package of journals the same as yours? What have I
licensed that isnt available? Flickr user dan_dan
Slide 18
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams Open Discovery Initiative The Open Discovery Initiative
(ODI) aims to facilitate progress through exploration of relevant
issues and the development of recommended practices for the current
generation of library discovery services based on centrally indexed
search. The domain of index- based discovery services involves a
complex ecosystem of interrelating issues and interests among
content providers, libraries, and discovery service creators.

Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams POLL: Before today, I knew about the Open Discovery
Initiative: A. A great deal B. Some C. Never heard of it before
today
Slide 20
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams Getting to What We Know We Have My colleagues & I
looked at link quality (a paper in review by ITAL in the spring).
Link resolution so-so quality (~60% success rate), open Direct
Linking high quality (90+% success rate), closed
Slide 21
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams Designing for Completeness How do we build our search
interfaces to accommodate everything? A few interesting approaches
out there

Slide 25
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams POLL: My librarys discovery tool integrates local &
licensed (non-catalog) content: A. Yes B. No C. I sure wish it
did
Slide 26
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams Integrate the Local & the Global The previous examples
start down this path What happens when you combine local resources
& global resources We see hyperlocal services in other areas;
why not libraries?
Slide 27
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams Better Slices of the Whole Sources & formats are the
easy way to slice the ocean But we could do more. Especially in
academia We [can] know a lot about our users Rich local sources of
context Course enrollments Course syllabi Professors Salted
starting points
Slide 28
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams Ways to Draw from the Ocean Courses Years of study Language
preference Academic standing Closely tied to institution
Slide 29
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams Streams Well-filtered searches make good current awareness
tools Libraries should be asking discovery vendors for: Need to
offer variable scope filters Flexible, locally customizable
Filtered views should not be default view for novice users
Slide 30
Ken Varnum@varnum Library Discovery: From Ponds to Oceans to
Streams Concluding Thoughts Discovery environments still emerging
What we do with them is all important Environment is ripe for
innovation
