CDL: Has anyone done a title analysis for PS A&I services?
From:
"Harker, Karen" <Karen.Harker_at_unt.edu>
I used to do overlap analysis of A&I's the hard way - by downloading title lists from each of the databases, and then matching them based on ISSN or title (not good). Now I've found a shortcut using Ulrich's. I search on the database name individually to get a count of the indexing of each database. Then I search*both* databases together. This is the overlap. Now I can calculate the overlap rate of each database.
Now, this is*not* (I repeat, NOT) exact. There are many layers which could result in errors. It is, however, a good rough estimate. In addition, it is overlap at the title-level only - there is no analysis of years or scope of coverage. Finally, there is no analysis of the quality or comprehensiveness of the indexing.
