Thought most everyone would have the COA pages bookmarked, but you are
correct, Bob, many probably do not.  In any case, this is the site for the
COA web page which has much to offer.  Lots of information and good links.
http://coa.acnatsci.org/conchnet/  They sponsor this list, so check it out.

If you are looking specifically for the Kaicher card index, it is under the
link, "Information Resources" at
http://coa.acnatsci.org/conchnet/eduinfo.html

Hope this helps,
