If you acquire the web version of Ulrich's, be aware about the "browse"
function.  We noticed that one can not browse the online directory of
Ulrich's.  You can only see the first 500 hits, which limited us from
browsing all the titles in a subject area.  I spoke to the technical staff
and they claim that if Bowker allowed us to browse all the titles in a
subject area, it would crash their system.  To remedy this problem, we had
to re-subscribe to the print source.
I am not sure if Ulrich's plans to correct this problem.
