We currently subscribe to IRIS  which has recently undergone a change
in its search procedure, extending search capablilities and not limiting
searches to keywords that are in the thesaurus.  Its boolean features
may be similar to SPIN's, but I found it less cumbersome to use.  They
also offer a Web version of IRIS which is extremely user friendly and
offers your office an easy way to open up search capability to all
facets of your campus.    I would encourage you to further investigate
the new  IRIS.
