Please excuse the off-topic post but I need help on research:

I think that's mostly what we do here.

A couple of years ago I ran across an online detailed catalog
description of each of the 45 or so CB&Q microfilm rolls and an
additional 15 or so on C.E. Perkins papers 1863-1907 with call
numbers in some online catalog of a library or college library.
AFAIK it was a simple Google search. I somehow lost the link and
cannot find it again after trying every conceivable search term and
variation thereof that I can think of. ...
Any ideas on finding this website beyond the normal Google, Bing,
etc. search engines???

Try <http://www.worldcat.org/>. It's a union catalog of hundreds of large libraries, with an emphasis on university and research libraries. I've found it an invaluable for seeing who has what.
