Applying Usage Data to Collection Management in Libraries & ConsortiaJason S. Price, Ph.D.Science & Electronic Resources LibrarianClaremont Colleges Libraries; SCELCBetter Data, Better Business: Applying Usage Data in Scholarly publishingJune 6, 2007 Society for Scholarly Publishing Annual Meeting. San Francisco, CA

Major questionsWhich titles should we keep or cut?Highest use/value vs. Lowest use/valueWhich titles should we add?Most requested (Traditional & Web)Which package provides highest or lowest value?

Use and ValueDetermining cost per useComparison with ILL costBy-title dataComparison across Publishershtml? pdf? combined (FTAR)?Need for context

Overall cost per use=1 years cost / 1 years requestse.g. $58,600 publisher E-access fee 35,700 article views $1.64 Cost per use* $420,000 mandatory cost of subs (to agent) for a subset of these same titles$420K + $ 58.6K = $478,600 / 35,700 = $13.40Determining Cost Per Use

Overall cost per view by Subs Type

Comparison with ILL costPackage CPV = $13.40What does this tell us?Is it High? Low? Better than ILL?

Challenge: Usage report granularityTitle-level use statisticsCurrently reported per titleCant separate frontfile use from backfile useBackfile may be previously purchased or freely availableUltimately cost per use should be based on what customers are paying forIssue of repository / free backfile use

Which titles should be added?Still largely determined by faculty requestJournal Report 2 (turnaways) is under-utilized by libraries and publishers(see example for Consortia near the end)

Cross-package comparisonSo Pkg 1 is a better value than Pkg 3?It might not be

Variation in use by formatDavis and Price, 2006 JASIST

html to pdf Ratios vary widely for these packagesHow many pdfs in Pkg 1 are duplicates of html views?

Live Link

S3. Package value revisitedpdf requests only tell a different story!

ImplicationsPublisher interface/content types can have major influence on cost per viewLinking tools can have significant disruptive effects on CPV calculationsIt is unclear whether pdfs vs FTARs are better for cost comparisonsTHUS: Within publisher comparisons are more valid than between publisher comparisons

Benchmarks for context

16: Low value?

16: High value?

16: The value of context

Questions for ConsortiaIs cost/value fairly distributed among members/participants?How can value/attractiveness be maintained or increased for current and future participants? License renewals do pricing terms need to be renegotiated?

Equitable distribution of value?

Year to year comparison

Year/Year by institution

ConclusionsPrice is an integral part of use evaluationRecognize that libraries need to base expenditures on actual return on costMeaningful cross-publisher comparisons are difficult (but will still be sought)Context is crucial for within-publisher comparisonConsortial statistics provide valuable benchmarksCross-year comparisons can indicate increasing valueUse consortial context to identify ideal institutions for additional sales (added titles, backfiles, etc)

*On the theme of negative impacts of the US on the UKId say this one is very specific,though Glad dont have to put into wordsOutline of rest of talk*Big deal Lock-ins & Combined Subscriptions *For the same publisher pkg in the same year*Not exactly red herrings*Use best calculated over multiple yearsTwo reasons not to give up: SwappingCooperative vendors

*Significantly different? What metric for use?*An option*Package with partial accessWhich titles should we add?
