DDA Programs: UCSD Gen. Coll. Background/Introduction
UCSD DDA Programs• Library goal: Make more titles available for discovery without purchase,
only purchase when needed • Three DDA programs in place, one more coming
• Commercial aggregators via YBP except for DDA4• Profile: Mirror library approval plan profile except for DDA4• Consideration pool file update
– New title file provided weekly by aggregators via YBP or OCLC– Delete file monthly only by one DDA program

DDA Programs: UC Gen. Coll. Background/Introduction
UC Consortia DDA Pilot Programs (CDL DDA)• Library goal: Maximize investments in digital content that enrich the
system wide library collection, accelerate the transition to a primarily digital environment, and optimize the use of physical library space
• Two DDA pilot programs in place
• Consideration pool file update– New title file weekly, add holdings to OCLC records– No delete file, identified title by title

DDA Programs: Models
• Three STLs + Mediated purchase: UCSD DDA 1– Free discovery: Browse up to 10 min. or 10 unique pages in single
session, free access to front/back matter (first or last 5% of the book)– STLs: More than 10 min. or 10 pages; print/copy/download one or
more page; cost: 10-15% or more• Three STLs + Auto-purchase: UCSD DDA 2-3, CDL DDA 1
– Same as the above for free discovery and STLs• Four-Six STLs + Auto-purchase: UCSD DDA 4
– STLs: 4 chapters download or 6 chapters viewed and NO COST• Evidence-Based Acquisitions: CDL DDA 2
– Pledge to spend a certain amount by the end of year – Titles didn’t get purchased are removed at the end except some being
included in the next year packageUCSD Cascading preference among existing three DDA programsPost-purchase: Single User Purchase Option (default), or optional unlimited or three concurrent users

DDA Programs Workflow
UCSD Workflow managed mostly by Acquisitions• Upload file weekly, MARC records provided• Monitor/initiate purchase and pay invoice• Catalog purchased titles• Troubleshoot any problems• Delete records manually and/or report to vendor
CDL Workflow (varies)• Catalogers login on content providers’ website to retrieve add title
list weekly, search OCLC to download records and add holdings• Acquisitions specialist monitors purchase and pay invoice• Bibliographers in DDA TF collect, process and analyze usage data
provided by content providers
6
DDA Programs: What works?
UCSD:• Free discovery/access to a larger pool of titles• Work with one vendor for three DDA programs
– MARC records provided regularly by vendors– Vendor has a designated person to facilitate troubleshooting – Library has access to all history records– Library can add title(s) outside profile
CDL:• Getting larger set of new materials from publishers, evidence of large portion
were used• Making titles available across system that each campus may not get • Option of not purchasing some titles being used (EBA DDA)• For overlapping titles, auto-purchase is triggered at system level • Both content provider and vendor are very collaborative when setting up the
programs• Discovery records are generally in good quality
7
DDA Programs: What improvements are needed?
• Control the cost increase of STLs– Modify the number of STLs for trigger– Alternative models: E-approval for certain subject areas
• Models that build STLs cost into purchase cost• Usage statistics (CDL EBA)
– Difficult to analyze incomplete data within given deadline– Usage data are cumulative and consortia members’ usage data on
separate files
• Understand the rules when they are not spelled out (CDL EBA)– List price increased without notice– If title purchased overlapping with what CDL has in other subscribed
package, who gets the credit?
• The availability of discovery records need to be in sync with titles added to the pool (both CDL DDA programs)

DDA Programs: Models
*The sale price for each book = this number times the list price;This multiplier may be but not necessarily the same as the no. of simultaneous users.
East Asian 1 (6 campuses) East Asian 2 (9 campuses)
Free discovery Unlimited Free discovery Free access up to 9 unique pages or shorter than 10 min. in the same book
Purchase • Auto purchase by preset triggers, and
• EBA - Based on usage, librarians make selection with the remaining balance on the pledged amount by the end of the contract year
Auto purchase by preset triggers
Consortial aspect
A multiplier of 2 (2 simultaneous users)
A multiplier of 1 (1 simultaneous user, another option; 2 for 3 users)

DDA Programs Workflow
East Asian 1 East Asian 2
License DDA programs
Lead by a librarian, assisted by local e-resource librarian and colleagues from campuses; MARC requirements attached
Lead by a librarian, assisted by CDL
Select consideration pool
Librarian reviews title list from vendor according to the profile
Librarian reviews and deselects unwanted subjects and resources
Load/Remove DDA records
Currently vendors records loaded to local OPACs by Shared Cataloging Program (SCP), existing consortial cataloging unit, who has set up a mechanism to remove 5-year-old records
Vendor-provided OCLC records loaded directly to local OPACs by SCP; records viewable in WorldCat; records will stay till the end of program
Monitor expenses, pay invoice
bimonthly vendor report on new purchase and usages; predetermined overspent cushion; preset cap of expenses; CDL-coordinated payment
Weekly vendor report on new purchase and usages; vendor notification of low deposit level; CDL-coordinated payment
Catalog purchased titles
SCP delete vendor DDA records; and then catalog purchase titles like any other e-resources
SCP update DDA records from OCLC to regular records for purchased titles

DDA Programs: What works?
East Asian 1• Careful plan of PDA profile• Close collaboration among librarian, TS representatives, and vendor• Test and retest in early stage (MARC, content, interface)• Ongoing reviewing and monitoring• Standardization (file name, record generation/loading procedure…), most
responsibilities transitioned to SCP as a result of issues from vendor’s workflow
East Asian 2• Platform works well for users across campuses• Leverage existing service across UC consortia (SCP) for DDA Records
management saved tremendous time negotiating, testing, and troubleshooting
• OCLC MARC records loaded by UC wide Shared Cataloging Unit eliminates incompatibility problems as well as provide access via WorldCat Local
13
DDA Programs: What improvements are needed?
EA1• Vendor was not on the same page technology wise• Had to compromise between what you want and what you
get (# of copies)• May have to include print version contents as not all print
books have equivalent e-books and a delay from P to E• Still early stage pilot, not sure whether where will be a
saving or overspending, etc.• Need OCLC # in MARC recordsEA 2• Multiple East Asian language e-books suppliers/vendors
with ability of providing MARC records and DDA programs
