Thinking about collections Lorcan Dempsey Fiesole retreat The University of Hong Kong 13 April 2007
Some topics • Reflections on collection directions • Systems support • Rareness is common • The long tail and library logistics • Access to scale: moving to the network level • Aggregate collections • Conclusions
stewardship high low Books Journals Newspapers Gov. docs CD, DVD Maps Scores Freely-accessible web resources Open source software Newsgroup archives low uniqueness • Research and learning materials • ePrints/tech reports • Learning objects • Courseware • E-portfolios • Research data Special collections Rare books Local/Historical newspapers Local history materials Archives & Manuscripts, Theses & dissertations high
Bought? • Opportunity costs • Digitization and offsite storage • Sharable > licensable • Licensed? • The ‘end of publishing’ - through the gates? Ingest into local collections New behaviors and support for research and learning Digital ‘record’ more important(prospectus, course catalog, student records) Focus of much digital library activity. Why? Distinctiveness.
Special: primary materials? Curatorial responsibility for more unique materials? Institutional Capacities? Collaborative sourcing? • Examples • Thematic research collection • Curated databases • Institutional ‘identity’
Managing digital? • An archival perspective? • Provenance • Evidential integrity • Versioning • Institutional capacities? • Collaborative sourcing?

Securing the scholarly record The scholarly record ain’t what it used to be? • Community? Institution? • Intervention required • Preserving print?
Mature? • Institutional maturity – an industry and cooperative structures • Structures under pressure • Libraries organized around this quadrant (‘owned’) • Emerging techniques for licensed • New systems framework for licensed Institutional immaturity • Organizational models for collective activity, reducing costs, etc, in development. • Commodity systems not available

4. The long tail and library logistics
Library “Inventory” 20% head 80% long tail Libraries aggregate supply at the local level… “About the only places you could explore outside the mainstream were the library and the comic book shop.” Chris Anderson, “The Long Tail”
The long tail Systemwide efficiences • Aggregation of supply • Unified discovery • Low transaction costs • Aggregation of demand • Mobilize users • Brand Impact?
Aggregate supply? 1.7% of circulations are ILLs (60% of aggregate G5 collection owned by one library only) Aggregate demand? 20% of collection accounted for 90% of use (2 research libraries over ~4 years) Each book its reader Each reader his/her book Libraries and the long tail dynamic
Note: All statistics are preliminary and subject to change. Final report forthcoming soon. The Library Long Tail(using holdings as measure of popularity) “Head” Number of Holdings Figure not drawn to scale; for illustration purposes only “Long Tail” Items ranked by system-wide popularity Head: Top 10% of WorldCat records (ranked by holdings) account for 80% of total WorldCat holdings Long Tail: Bottom 90% of WorldCat records (ranked by holdings) account for 20% of total WorldCat holdings
Note: All statistics are preliminary and subject to change. Final report forthcoming soon. ILL and the Long Tail(FY 2005 OCLC ILL transactions) ~75% of ILL requests were directed at the “Head” Number of Holdings ~25% of ILL requests were directed at the “Long Tail” Items ranked by system-wide popularity By comparison, Chris Anderson (The Long Tail, 2006) reports: Amazon: ~ 25% of sales from the “long tail” Netflix: ~ 20% of sales from the “long tail” * Question: are current ILL systems adequately supporting demand for the library long tail?
Conclusions 5. Access to scale: moving to the network level
Libraries Librarian readers Cataloguer, repository, collection, … Moving to the network level In the lone houses and very small villages which are scattered about in so desert a country as the Highlands of Scotland, every farmer must be butcher, baker and brewer for his/her own family. Adam Smith
Trajectory … Then • Cataloging & resource sharing • A&I and e-Journals • Collections Now • Growing realization that much more can be done at the network level

Collection development Mass digitization Off site storage Discovery to delivery Find it – get it Preservation Thinking about collections in aggregate or systemwide terms Opportunity costs Space Attention/value On demand Print on demand Buy on demand Digitize on demand Management data: holdings, circulation, … Aggregate collections
Best practices + organizational contexts for: • Off site storage (see NAST, UKRR) • Mass digitization • Preservation (see Portico, CLOCKSS, …) • D2D ?
The scholarly record: what is it and how is stewardship exercised? • Recalibrate local and ‘collaboratively’ sourced • Systemwide/network level • Plural business and delivery models • Develop a more instrumental view of organizations at the network level?
