The online catalog is not up for the next Profiles auction yet.
But at their site
http://profilesinhistory.com/ you can see a preview of some of the star wars items they are going to have.
Usually the catalog is up online to view in pdf format 3 weeks or so before the auction date. A few days before that the catalogs should arrive if you buy one or get one because you won something in an auction before.
A little bit after the online catalog is up the items should be available to view via ebayliveauctions. This is helpful because you can see what the starting bid prices will be exactly as you only have an auction estimate price available in the catalogs both printed and in pdf format.
