DESCRIPTION

With the goal of building a high quality academic library collection in mind, the presenters evaluated the value of journal content accessed through journal aggregator database(s). Data from aggregator provider(s) and data from UlrichsWeb was used to evaluate content with respect for quality, format, coverage and cost. In addition the presenters shared the analysis with library liaisons to inform them of true holdings to assist them with collection development.

<ul><li> 1. Aggregators: Cornerstone or Annex? Beverly Geckle Suzanne Mangrum </li></ul> <p> 2. Questions/Purpose: E-journal collection assessment and collection development project focused on e-journal aggregator content. Aggregators have become a standard in the librarys collection, but what have we really purchased? Analyze aggregator content by subject and quality. 3. Aggregator Online Dictionary for Library and Information Science. http://www.abc- clio.com/ODLIS/odlis_A.aspx A bibliographic service that provides online access to the digital full-text of periodicals published by different publishers. Because aggregator databases can be very large, tracking their coverage is not an easy task for serials librarians. A task group of the Program for Cooperative Cataloging (PCC) is working on standards for analytic catalog records for serials titles available electronically from aggregator services. Currently, the top two journal aggregators in the United States are EBSCO and ProQuest. Recently, EBSCO has been building market share by offering higher up-front payments to secure exclusivity from the publishers of certain journals. The effects of this competitive practice on libraries and the end-user are as yet unclear. 4. Chosen Aggregator http://www.ebscohost.com/academic/academic-search-premier 5. Data Parts ASP UlrichsWeb Quality Full Text Impact factors Subjects Journal Citation Rpts 6. Data Parts ASP UlrichsWeb Quality Full Text Impact factors Subjects Journal Citation Rpts 7. ASP Basic Criteria ASP Quality Full Text First, we were interested in the ASP data that matched our basic criteria for quality: Full-Text Peer-Reviewed PDFs 8. Data Parts ASP UlrichsWeb Quality Full Text Impact factors Subjects Journal Citation Rpts 9. Data Parts - UlrichsWeb UlrichsWeb Subjects Business &amp; Economics Social Sciences &amp; Humanities Government, Law, &amp; Public Administration Education Sports, Leisure, &amp; Recreation We used UlrichsWeb to limit our data to certain subjects. We decided to focus on the Social Sciences. We selected the following subject groups: 10. Data Parts ASP UlrichsWeb Quality Full Text Impact factors Subjects Journal Citation Rpts 11. Data Parts Impact factors We used Thomson Reuters ISI Journal Citation Reports (ISI) to identify the very best journals by impact factor. We chose multiple subject sets that fell within the broad subject of social science. Journal Citation Rpts 12. METHODOLOGY 13. METHODOLOGY Filtering Data downloaded Needed massaging Filtered each data source to create subsets Matching Subject Subsets matched to identify high quality (high impact) titles The resulting subsets were then matched for coverage 14. Methodology - Filtering ASP Coverage Dates UlrichsWeb Subjects in ASP Journal citation reports Top 25 of chosen subjects 15. ASP - Filtering ASP ISI Top 25 UlrichsWeb Quality Full Text Impact factors Subjects 16. Further broken out by coverage Total ASP Full Text Peer Reviewed PDF images end date embargo to present 17. Coverage Used data from ASP spreadsheet to also filter by coverage. ASP ASP title list: ASP Full Text Titles that are peer reviewed and available as a PDF 18. Limited to Full Text titles 4768 titles Marked values using Conditional Formatting in Excel Then sorted the columns by marked values to filter coverage categories 19. Full Text &amp; no end date 3674 titles 20. Full Text not embargoed 1734 titles 21. Full Text to Present, PR and PDF 1262 titles 22. Repeated process for additional categories: Titles with an end date (Full Text Stop Titles embargoed (Full Text Delay) 23. Ulrichs III query against SS MARC records in ILS Ensure that an end date was truly a coverage limitation we removed ceased titles. Focus on current titles 24.

ISI Journal Citation Reports ISI provides the rankings by subject, which was not in our Ulrichs data 34. After combining all of the reports, we had over 1200 titles that ranked in the top 25 of our categories Some titles were listed in more than one subject area, so we deduped the titles but retained all subjects. 35. Methodology - Matching Each filtered Ulrichs subject list was matched with the ISI top 25 spreadsheet These became our subject lists of high quality titles 36. Ulrichs Business &amp; Economics 1047 EBSCOhost 891 ASP (full text) 104 UlrichsWeb ISI Combined ISI Top 25 List 37.

Implications for Collection Development Discovery vs. Access Discovery &amp; Cost Implications 46. Discovery vs. Access Linked Full Text 47. Although ASP enabled discovery full text was made available because Library subscribes to the SAGE Premier 2013 package 48. Discovery vs. Access 49. Discovery vs. Access A search in the Journal A-Z List shows that it is embargoed 50. Discovery vs. Access 51. Discovery vs. Access A search in the Journal A-Z List shows that it is embargoed 52.

What is the library really purchasing? Indexing, discovery, content. Need for better understanding of both discoverability and access. 57. Thank you!
