Overlap analysis of online journals

[VanderHart, Robert]

Serials Solutions ejournal management system offers a feature called
Overlap Analysis, which allows you to compare databases to see where
they overlap in coverage.

I'm interested in hearing opinions from Serials Solutions customers on
this feature.  How useful have you found it?  Does it really aid you in
collection development?  

I'm also interested in hearing from anyone who's implemented a similar
feature in-house (i.e. "homegrown").  What system are you using (PHP,
ColdFusion, Perl)?  How difficult was it to set up?

Thanks in advance for any feedback.  Have a nice holiday!
