Hi Rebecca,

I often use and Excel forumula to compare unique identifiers in urls between a publisher list and a KB list for a particular database.  I've never tried to compare coverage dates this way however because of the discrepancies in the way the data is entered.

The formula compares all data in one column with all data in another column on another sheet (or not) and gives a TRUE/FALSE result for matches.  It must be entered as an array formula.

The basic formula is 
=OR(EXACT(A2, Sheet2!A$2:A$10))
after entering in a cell, hit F2 and Ctrl Shift Enter resulting in an array formula
{=OR(EXACT(A2, Sheet2!A$2:A$10))}

This may help to solve some of your problem as I never found that I could get VLOOKUP to work properly if I was trying to match many datapoints at once.

Best,
Chris

Dear Colleagues,

Do you have a good method or set of procedures worked out for comparing e-journal entitlements lists against what is activated and/or able to be activated in your knowledge base (KB)?  I'm defining "entitlements lists" as lists of the e-journal titles and the subscribed/purchased coverage to which we are entitled.  These lists can be e-mailed by publisher representatives or downloaded from publisher websites.  Our knowledge base is WorldCat KB, and the KB files we compare against are KBART files, but I am interested in looking at procedures that anyone may be using, regardless of which KB you have.

We have tried using Excel's VLOOKUP functionality to match titles by unique identifier, but it seems as though there are lots of problems ​in the vendor supplied data ​that make it hard to compare coverage (and even titles, sometimes). A few problems we've run up against are entitlements lists that do not show all title changes with separate titles, ISSNs, and coverage for all the titles in the history, and entitlements lists that show separate lines for each subscribed year of the title, which makes it hard to pull together the true start date and end date into one KB entry.

If you have a process that you think works pretty well for matching up entitlements with what's available in the KB, would you mind contacting me?  I would love to learn about your process(es) and the tools you use. We are especially interested in automating the process with Excel or Google Sheet templates, if anyone has been doing that.​ Or are there any workshops or presentations that anyone knows of on this topic?

Has anyone had any success in getting better entitlements data from publishers?

Let me know if I need to clarify my request. Also, if there is interest in my gathering together responses and sharing to the lists, I would be happy to do that.

Many thanks for considering,
Rebecca
