Which is the correct URL to be using www.mudcat.org or the http://www.deltablues.com/dbsearch.html? I thought Mudcat was going to be off deltablues.com and onto mudcat.com?

As was pointed out to me, when you go to www.mudcat.com mention is made of the April 1997 database. When you go to the deltablues.com a similar page pops up but with reference to the October 1997 database.
