  • Comparing Bananas With Grapes

    1. 1. Comparing Bananas with Grapes: Ebook Use Data from a Bunch of Vendors Joseph Kraus University of Denver Penrose Library November 6, 2009
    2. 2. Introduction <ul><li>I will be putting this presentation onto Slideshare. </li></ul><ul><ul><li> </li></ul></ul><ul><li>I would like to make this a discussion, not just me talking. </li></ul><ul><li>You can read the paper. This is not just a rehash of individual ebook use and section use data. </li></ul><ul><li>If you want even more data, I will put more book titles on the web somewhere. </li></ul><ul><li>Images are used with CC licenses. </li></ul>
    3. 3. Why did I do this?
    4. 4. Why? <ul><li>I wanted to get a better sense of what topics the computer science and engineering students and faculty find useful. </li></ul><ul><li>For other projects, I’ve looked at faculty citation data and journal article download data. Since we have been adding many ebook packages, I wanted to analyze our ebook use data. </li></ul>
    5. 5. What’s up with comparing bananas with grapes? <ul><li>The vendors provide the data in lots of different ways and formats. </li></ul><ul><li>Tough to analyze the data. </li></ul><ul><li>Didn’t want to compare apples with oranges because they don’t come in bunches. </li></ul>
    6. 6. Info on the bananas <ul><li>The bananas are large fruit, and they can’t be eaten in a single bite. These vendors provide section usage. There is no data on individual ebooks. </li></ul>

    10. 10. Info on the grapes <ul><li>The grapes are smaller fruit that can be examined and eaten individually. Most vendors provided individual ebook COUNTER compliant usage statistics. The print book circulation data is not COUNTER compliant. </li></ul>

    14. 14. Difficulties evaluating the data
    15. 15. Difficulties evaluating the data <ul><li>They have different field titles for ebook use. </li></ul><ul><li>The vendors provide different numbers of book titles. </li></ul><ul><ul><li>We have about 100 Morgan & Claypool titles, while ENGnetBASE is over 900, ebrary has over 45,000 titles </li></ul></ul><ul><li>They provide different years of coverage. For example, Safari averages about 2.5 years. </li></ul><ul><li>Cost is a factor. Subscription vs. purchase models. </li></ul><ul><li>Number of seats or ports (2 seats or unlimited). </li></ul><ul><li>Content is viewed and navigated in different ways. </li></ul><ul><li>Print book check out times vary (2 hours to one year.) </li></ul>
    16. 16. Did I forget anything?
    17. 17. What would I do differently next time? <ul><li>Have more catalog records </li></ul><ul><li>Get statistics for Books24x7 </li></ul>
    18. 18. More changes are ahead
    19. 19. More changes are ahead <ul><li>Springer ebooks </li></ul><ul><li>State-wide academic library cooperative collection development </li></ul><ul><li>Patron driven collection development </li></ul><ul><li>Google books </li></ul><ul><li>Kindle, B&N Nook, Sony eReaders, iPhones, etc. </li></ul><ul><li>Book reading behaviors are changing. Are engineers and CS / IT people ahead of the curve? </li></ul><ul><li>Does it depend on the sub-discipline? </li></ul>
    20. 20. Tools to help evaluate the data <ul><li>Spreadsheets (What I used for the paper) </li></ul><ul><li>ScholarlyStats (We are considering) </li></ul><ul><li>Spectra Dimension from Library Dynamics (Have) </li></ul><ul><li>III ERM and SUSHI statistics (Have) </li></ul><ul><ul><li>Serials librarian is running this. </li></ul></ul><ul><ul><li> </li></ul></ul><ul><ul><li>e-journal usage statistics for the most part </li></ul></ul>
