- 2. 2016 Study: How Easy is it to Access Journal Articles for Free?
- 8. 2016 Study What proportion of the journal literature is freely available? ● ● ○ ○ ○ ● ● ○ ○
- 12. • • • •
- 13. A proposition . . . Given that more than half the literature is freely available... ➣ To lure researchers back to our (richer) DS we’ll need ALL OA to be discoverable through our systems (in addition to the content we license, which in combination should rival Sci-hub)
- 15. 2017 Study How successful are libraries (and their vendors) at providing access to Gold OA articles through their discovery systems? Gold OA articles: hosted on publisher’s site ● Can be in either a fully open or a hybrid journal
- 16. 2017 Study ● 144 libraries invited ○ Half large/extra Large, Half small/very small ● 8 publishers: ○ De Gruyter, Elsevier, Nature, Oxford, SAGE, Springer, T&F, Wiley ● 320 articles, no more than 1 article per journal ○ 270 of these were gold OA ■ 160 from fully OA journals, 110 from hybrid journals ■ 4 sets of 80 articles, each assigned to 40 libraries ■ All 320 articles searched in Google Scholar as a control ● Test for ○ Indexing in discovery service ○ Access to full text of publisher version and any version ○ Defined access as reaching FT in three clicks or less
- 17. Data Set Description 2016 study ● 300 articles indexed in Scopus published in 2015 ○ A&H, SS, Life Sciences ● No limit by publisher 2017 study ● 320 articles published in 2015 ● From 8 major publishers ○ Hybrid and Fully OA journals ● Split into 4 stratified random samples
- 18. Responses So Far ● 66 libraries in North America responded ○ 58 completed searching ■ 48 verified ■ 10 need additional verification ○ 8 provided guest credentials ● 9 declined
- 19. Today’s Sample ● 40 Libraries in North America ○ 10 small (range of materials budget: $100K-599K) ○ 10 medium (range materials budget: $600K-2.4m) ○ 10 large (range of materials budget: $2.5m-8.9m) ○ 10 very large (range of materials budget: $9m-20m) ● Why sizematters
- 21. 2017 Study 1) Do library discovery systems index as many gold OA articles as Google Scholar does? 2) Do library discovery systems provide full text access to as many gold OA articles as Google Scholar does?
- 22. 1) Do library discovery systems index as many gold OA articles as Google Scholar does?
- 23. 2) Do library discovery systems provide full text access to as many gold OA articles as Google Scholar does?
- 24. By the numbers
- 26. Does full text access to gold OA articles differ between fully OA and hybrid journals?
- 27. 2017 Study Are OA articles from hybrid journals more or less accessible than articles from fully OA journals? And is this related to institution size?
- 30. Conclusions of 2017 Study ● 85-100% of gold OA articles are indexed in library discovery systems ● 50-90% of gold OA articles are accessible from library discovery systems ● In general, smaller schools have access to fewer articles ● For these major publishers, indexing is fairly consistent across libraries ● Lower rates of access could be due to many factors related to linking
