Gathering
• Solution 1– Gathering & manipulating data was time
consuming & difficult– Database structure did not reflect our
subscriptions, so it didn’t work for us
• Solution 2– Vendor did the hard parts
– Spreadsheet, delivered twice a year, can be sorted by title or publisher, which works for us
– We have requested that subject information be included to help with collection development.

Future
• Counter Reports:– Counter JR2 & BR3 Turnaways. We would like to see more publishers
provide this data. We can use it for collection development. – Counter JR5 Number of Successful Full-Text Article Requests by Year-
of-Publication & Journal. Now we can finally see current year usage vs. older/but recent content.
– Counter J/BR1 (optional) Number of Successful Full-Text Item Requests by Month & Title. We don’t care if it’s a book or journal, we care about the download. We are gathering JR 1 & BR1 anyway, and
we are looking at individual titles to assess a cost-per-download.
• New for 2010 (for SwRI)
– Referex: We recently added Referex, an e-book subscription package that only offers search data, no download data. How do we evaluate
this full-text resource with only search data?– E-book purchases: In this case, we are making the purchase up-front,
and then getting usage data. How will we evaluate usage/cost in this case?
