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.

  • The title/cost ratio of an aggregator makes them attractive, but the quality of the resource is not as transparent. Analyzing based on just number of titles and costs only tells part of the story. We wanted a more in depth, granular methodology to analyze the content of aggregators by subject and quality.
  • We chose Academic Search Premier (ASP) from EBSCO Publishing because it is enormously popular at our library and data about the content was easily available for download.

  • Thank ASP for including the peer reviewed and PDF availability as well as full text.

  • Additionally titles with an end date may not have current content because they are ceased titles and title changes. We filtered those titles out of the list using Ulrichs and Serials Solutions MARC records

  • By using Ulrichs we could pull out journals of a certain subject, journals that were in ISI, and were also in EbscoHOst.

  • Example 2
  • As CDM librarians we need to know what to buy. Work and Stress is ranked 9th in JCR’s Applied Psychology list. We’re paying for indexing in 4 databases, but a simple overlap analysis may not uncover that it is embargoed in every one.
  • Example 2
  • This is an example that we will bring up with a liaison since we have a PhD in this area. This journal is ranked 13th in the JCR Special Education list.
  • The aggregator database cornerstone or annex

    1. 1. Aggregators: Cornerstone or Annex? Beverly Geckle Suzanne Mangrum
    2. 2. Questions/Purpose: • E-journal collection assessment and collection development project focused on e-journal aggregator content. • Aggregators have become a standard in the library’s collection, but what have we really purchased? • Analyze aggregator content by subject and quality.
    3. 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.

    7. 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. 8. Data Parts ASP UlrichsWeb Quality Full Text Impact factors Subjects Journal Citation Rpts
    9. 9. Data Parts - UlrichsWeb UlrichsWeb Subjects • Business & Economics • Social Sciences & Humanities • Government, Law, & Public Administration • Education • Sports, Leisure, & 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. 10. Data Parts ASP UlrichsWeb Quality Full Text Impact factors Subjects Journal Citation Rpts
    11. 11. Data Parts Impact factors We used Thomson Reuter’s 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. 12. METHODOLOGY
    13. 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. 14. Methodology - Filtering ASP – Coverage Dates UlrichsWeb – Subjects in ASP Journal citation reports – Top 25 of chosen subjects
    15. 15. ASP - Filtering ASP ISI Top 25 UlrichsWeb Quality Full Text Impact factors Subjects
    16. 16. Further broken out by coverage Total ASP Full Text Peer Reviewed PDF images end date embargo to present
    17. 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. 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. 19. Full Text & no end date 3674 titles
    20. 20. Full Text not embargoed 1734 titles
    21. 21. Full Text to Present, PR and PDF 1262 titles
    22. 22. Repeated process for additional categories: • Titles with an end date (Full Text Stop • Titles embargoed (Full Text Delay)
    23. 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. 24. ASP Filtered Subsets Total ASP Full Text Peer Reviewed PDF images end date embargo to present
    25. 25. UlrichsWeb - Filtering ASP ISI Top 25 UlrichsWeb Quality Full Text Impact factors Subjects
    26. 26. UlrichsWeb – Filtering
    27. 27. We downloaded the filtered subject list from Ulrich’s and used Conditional Formatting to pull out all titles available in Academic Search Premier.

    33. 33. ISI Journal Citation Reports ISI provides the rankings by subject, which was not in our Ulrich’s data
    34. 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. 35. Methodology - Matching Each filtered Ulrich’s subject list was matched with the ISI top 25 spreadsheet These became our subject lists of high quality titles

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

    54. 54. Results – Subject Perspective
    55. 55. Results – Subject Perspective
    56. 56. More questions than answers? • What is the library really purchasing? • Indexing, discovery, content. • Need for better understanding of both discoverability and access.
