Rethinking Collection DevelopmentLong-standing “just in case” approach
“80/20 statistics” “Overselection” vs. “Underselection”Emphasis shifted to demand-based funding and selectionTowards effective collection development
8Slide9
Effective Collection DevelopmentTo ensure a “return on investment”Measured by collection use
Aim to avoid Type I and II errorsType II errors: titles acquired but not usedType I errors: titles used but not acquiredCan be measured using circulation data and interlibrary loan data (ILL)9Slide10
Measuring Collection UseCirculation statistics
Titles that library acquired and used Can identify needs in various subject areas Can identify user groups (student or faculty)ILL titlesReflect user needs that the library doesn’t ownCan identify user groups
10Slide11
Study QuestionsWhat do ILL book requests and circulation data tell us about our collection use and patron needs?
How can data analysis inform our collection development practices to better serve our patrons? 11Slide12
Beginning AssumptionsEffective collection development can be measured by collection use
Collection use = meeting user needsUser needs represented by titlesowned and circulated not owned but borrowed via ILL12Slide13

Data ScopeIncluded all faculty, graduate student and undergraduate transactions for books circulated and borrowed via ILL having imprint dates of 2007 onward
Eliminated LC classes A, C, S, U, V because of very low acquisition rateEnd result represented 82% of purchased books and 30% of books borrowed on ILL Slide20
MeasuresTotal user needs in a library
Circulation of local library materialsILL requests for library materials that are not locally availableFocus on recent acquisitionsSlide21
Testing the AssumptionsWhat are we buying?What are we circulating?
What are we borrowing on ILL?How well have we done in collection building to meet user needs?Slide22

Another Way of Looking at the DataIf Lending = User needs
met andLending = Circulation + ILLThen (ILL / (Circulation + ILL)) = the part of lending that is ILL or the portion of user needs not met by our collectionSlide30Slide31Slide32Slide33Slide34Slide35Slide36
Some RethinkingMaybe we’re looking at this incorrectly
Maybe all borrowing (via ILL or our acquired collection) is not equal, not all “need”Maybe we’re looking at “The Long Tail”Slide37

Caution in using ILL DataPurpose of ILL serviceTo meet academic needs (e.g., multidisciplinary titles)
To meet user needs of general interest outside curriculum scopeFor recreational purposesTake above factors into consideration when considering user-initiated acquisitionsSlide44
Early ConclusionsWe have made some inaccurate assumptions
all need is not equalThe question is not “What should we buy?” but “Should we buy?”We cannot judge the usefulness of a book without expert mediation
Findings can shed light on effectiveness of collection development practicesSlide45
Post Study QuestionsWhat constitutes a good academic collection?
Should ILL requests continue be seen as needs in the long tail or are we looking at the cutting edge?If ILL needs represent more than just long tail, should the library re-examine our collection development policy? Slide46
