Intriguing! This could certainly be done in Access; you would need at
least four tables: Composers; Works; Instruments; and Instrumentation.
It would be reasonably straightforward to build a form based on these
tables to replecate the functionality of the website (with subforms
and combo boxes or listboxes to select the records).
It's more than would be appropriate for a newsgroup post, but here are
some resources to get started. Allen's and Crystal's tutorials should
get you off the ground, and you're welcome to post back with specific
questions.
