Jeremy Butler and others,
Re: accessing the Library of Congress.  There is a limited access to the
LC title/author catalog by the public by TELNETing DRA.COM.  DRA.COM is a
private firm that has licensed the LC catalog and sells membership to
libraries.  Whether individuals can also subscribe I don't know.  As a sort
of come on device, DRA.COM permits on subscribers to do title and author
searches free of charge, but not subject searches.  To do that you have to
be a subscriber.  Insofar as about 200 libraries allow you do do subject
searches for free over Internet, I'm not sure the LC catalog subscription
is really worth the cost.
