Uniquely-Held Print Books:  Assessing System-wide Holdings in ARL InstitutionsUniquely-Held Print Books: Assessing System-wide Holdings in ARL Institutions Presentation Transcript

  • RLG ProgramsUniquely-Held Print Books:Assessing System-wideHoldings in ARL InstitutionsJim MichalkoV-P, RLG Programs
  • RLG Programs ARL Special Collections Working Group2007-10-092Project Background Immediate stimulus: IMLS Connecting toCollections grant program State-wide planning grants to support implementation ofHeritage Health Index (2005) recommendations OCLC Programs & Research work agenda:Managing the Collective Collection Last copies analysis Shared print collections, cooperative collection mgt Past work: Connaway, O‟Neill, Prabha “LastCopies: What‟s at Risk?” College & ResearchLibraries, 67, 4 (July 2006): 370-379. Examined unique holdings at Vanderbilt university;established methodology for ongoing work
  • RLG Programs ARL Special Collections Working Group2007-10-093Relevance to ARL Special CollectionsCoordinated action is needed to identify, preserveand effectively disclose ‘last copies’ in researchlibrary collections 70% or more of uniquely-held titles in the WorldCatdatabase are held by research libraries Policies and infrastructure for coordinated action on lastcopies within the research library are lacking As distinctive holdings, last copies represent both a localinstitutional asset and a tangible public good around whichjoint action can be organized
  • RLG Programs ARL Special Collections Working Group2007-10-094Sample Characteristics Fractional sample drawn from January 2007snapshot of WorldCat (prior to integration of RLGUnion Catalog) Records for uniquely held titles at ARL institutions= 13,283,782 records Limited to print books (excludes othermonographic formats, e.g. manuscripts catalogedas books, e-books) = 6,950,632 records Further limited to exclude theses & dissertations Final sample: 6,518,341 records Represents unique print book holdings at 123institutions and 333 OCLC library symbols
  • RLG Programs ARL Special Collections Working Group2007-10-095Overview of Results Geographic distribution US & Canada Adjusted for ARL distribution Institutional distribution ARL as a whole RLG Partners Distribution by content type and age Theses and dissertations (“only copies”) Recent publications (“first copies”) Distribution by holdings Top-, mid- and bottom-tier characteristics Questions for consideration
  • RLG Programs ARL Special Collections Working Group2007-10-096Geographic DistributionLooking at the regional distribution of uniquely-held booksmay suggest opportunities for local and group action US & Canada (123 ARL institutions) US holdings are concentrated on the East and West coasts Canadian holdings account for 13% of aggregate ARL holdingsand are more dispersed Adjusted for ARL distribution Highlights states with few ARLs but many unique holdings States with a high density of unique holdings relative to thenumber of ARL institutions may require additional investmentin infrastructure

  • RLG Programs ARL Special Collections Working Group2007-10-0910Institutional DistributionLooking at institutional holdings in the context ofthe aggregate unique print book collection providesa shared view of collective assets and opportunities ARL members (123 institutions) Total unique print books = 6.4M titles Represents 1% of reported 2006 ARL volume holdings Median institutional holdings = 17,275 titles RLG members of ARL (37 institutions) RLG ARL unique print books = 3.9M titles Represents 60% of aggregate ARL unique book coll‟n Median institutional holdings = 40,366 titles

  • RLG Programs ARL Special Collections Working Group2007-10-0913Distribution by Content Type and AgeSeparating different strands within the sample highlightsdifferences in local collecting and cataloging practices acrossthe ARL membership: Recent publications (2000-) account for 19% of theaggregate ARL unique print book collection; institutionswith aggressive monographic acquisition and catalogingpolicies hold most of these “first copies” While theses and dissertations represent just 6% of theaggregate ARL unique print book collection, they are anotable part -- up to 60% -- of holdings at institutions thatmake a special practice of acquiring them (e.g., CRL)

  • RLG Programs ARL Special Collections Working Group2007-10-0915Distribution of Unique Print Books in ARL Member InstitutionsIn the top quintile, Total unique print bookholdings vary widely (from600K titles to 90K) Relative contribution oftheses and dissertations(5%) is low and stable Relative contribution ofrecent publications (11%)to unique holdings ismodest and stableLarge institutions with deep collections and sustained growth
  • RLG Programs ARL Special Collections Working Group2007-10-0916Distribution of Unique Print Books in ARL Member InstitutionsIn the middle quintile, Total unique holdings varyless (from 23K to 15Ktitles) Relative contribution oftheses and dissertations islow (4%) but variable(from 0 to 10%) Relative contribution ofrecent publications ismodest (11%) and stableMid-tier institutions looking to build research capacity
  • RLG Programs ARL Special Collections Working Group2007-10-0917Distribution of Unique Print Books in ARL Member InstitutionsIn the bottom quintile, Total unique holdings dropsharply (from 8K to 400) Relative contribution oftheses and dissertations islow (3%) but varies widely(from 0 to 52%) Relative contribution ofrecent publications (13%)is higher than in othergroupsSmaller institutions with younger collections
  • RLG Programs ARL Special Collections Working Group2007-10-0918Questions to Consider How to prioritize decision-making aroundmanagement of unique holdings What kind of data is needed content type, publication date, subject area, etc preservation infrastructure, environmental conditions, etc What kind of context is important regional consortial Aggregating long-tail supply and demand Opportunities for partner collaboration – hidden coll‟ns Shared storage – virtual or physical consolidation Measuring library leadership volumetric assessment vs. quality of care/management
  • RLG Programs ARL Special Collections Working Group2007-10-0919Food for thought: ARL SCWG data
