Hopefully others can help with more general recommendations, but I
suggest you take a look at.....

.....although there are some SGI-only images and animations in there,
it's got a lot of good, impressive, content-filled (I can say that
since I didn't create it) multi/hypermedia stuff that can be viewed on
any color platform.

If you have a valid NNTP/netnews server available to you, set
environment variable NNTPSERVER to it before starting Mosaic and then
you can access any group with URL's of form......


......or whatever.

CERN (the source of those documents) had machine problems today.  I
see they're back up now (2:30am Central time).

Others can maybe help there -- the global answer is that the Internet
isn't yet a library in any reasonable sense of the word is because
nobody's paying anyone to make it a library.  Hopefully through the
use of technology like WWW/WAIS/Gopher etc. this will one day happen.
But there are pockets of definite non-technical content here and

Suggest you contact us directly (  Sounds like
a strange problem.

Suggest you contact us directly wrt this too -- the threshold from our
side is that if a commercial concern is distributing and/or modifying
Mosaic in a commercial context, as part of commercial activities, then
it's probably be a good idea to come talk to us.  Everything else is
free (including internal company use, btw).
