1 The evidence is in: Patron Driven Acquisition Promotes Collection Use Jason Price & John McDonald Claremont University Consortium SCELC Colloquium - March 2, 2011 (with thanks for data & discussion from Kari Paulson & Alison Morin of EBL)

2 Bananas tipped the boat: a cautionary tale Early patron-driven deal with a major platform Assignment on economics of banana plantations UC Boulder ‘bought every book with banana in the title’ Used by librarians & vendors(!) as evidence that user-driven selection is a bad idea

3 Patron-driven model objections: cautionary conclusions? Books will be selected based on click-thrus that don’t indicate interest Users will select ebooks that no one (else) is interested in User selected collections will be unbalanced turkeys

4 Definitions Purchase type Patron selected = Demand Driven = User-selected Librarian selected ≈ Library selected ≈ Pre-selected Ebook usage was measured conservatively Data reflects post-purchase use –Did not count uses that lead to user-selection ‘Casual’ use eliminated –1 use ≈ 1 ‘read online’ ≈ 1 ‘download’ –read online = >10 min w/click thru OR copy OR print Transaction level data –each use recorded separately with user anonymously identified

5 Questions we’ll address 1.Are user-selected ebooks used less often than pre-selected ebooks? 2.Do user-selected ebooks have a narrower audience? 3.Are user-selected collections less balanced? Do we have anything to fear in patron-driven selection? (Can we use this to build better acquisition models?)

6 Scope of the overall dataset 1 Ebook Vendor – EBL (Ebook Library) 11 Libraries 28,327 ebooks bought from 2006 - 2009 212,887 uses during that period Purchase Models: User Selection, Pre- Selection, or Mixed

26 Summary 1.Are user-selected ebooks used less often than pre- selected ebooks? No. User-selected ebooks are used 2-5x more often 2.Do user-selected ebooks have a narrower audience? No. User-selected ebooks are used by 2-3x more unique users 3.Are user-selected collections less balanced? No. User selected collections are similarly balanced.

27 Questions & Discussion Given our results – what do we still have to fear from patron-driven purchasing (at least in the EBL model)?
