9  Data may be unhelpful, or misleading  Links may not work  This may change over time

10  From one book:  Title  Author  Series  Subject headings  From another book:  Notes  ISBN  Link to e-book

11  Provider-neutral records may have URLs from multiple vendors  An OCLC search for records with URLs from eblib, ebrary, ebscohost AND myilibrary returned over 43,000.  Even if they are labeled, patrons don’t know which vendor we’re using

16  Some ebooks on a frontlist may never appear on the site  Individual ebooks may just disappear

17  But not forthcoming.  You may have to periodically dig several levels deep on the website to get them:

18 After we confronted one vendor: “Of the 15 accounts that I spot checked the most usage for (TITLE) was 5 views. However, I see that the 2 titles listed below are in the top 5 most viewed for UKY in 2012.”

19

20  Start with the best records you can find  Edit MARC records to conform with local standards  Verify access to all titles (periodically)  Report problems when you find them

21  But how do you predict what you will need?

22  Developed by Terry Reese  MARC editing in a friendly yet powerful text editor  Z39.50 client  (Binary editor!)

23  Efficiency, Consistency .mrk format is text, so you can process with your favorite programming language  Don’t have a favorite language (yet)?

24

25  NORMalization and Access Checking  Open source software, releasing soon  Configure per vendor:  Fields to add/delete  Changes to make  How to check links

26  Ebook errors can be valid web pages, and errors don’t mean you should give up!  HTTP/ OK  Full text ebook  Web site form to buy the book  HTTP/ Not Found  No such page on server  Broken DOI (that you should report)

27  Database holds a list of links to be checked  Script checks each according to site profile (pausing 10 seconds between each link):  Is it a PDF?  Does it contain the phrase “This is not part of your subscription”?  Can you click through to fulltext chapters?

28  Let me know!  I have to know what broken ebooks look like (from a given vendor) before I can detect them  If a vendor has many broken ones I can do a systematic check
