My summary on gluten free product guides is as follows:

(1) Several said they use both CSA Guide as well as the Tri-County Guide.  The site for CSA Guide is www.csaceliacs.org and phone is 402-558-0600.  The site for Tri-County is http://community.mlive.com/cc/celiac
  
(2) The Clan Thompson was mentioned as a good source

(3) The Products list at http://www.celiac.org

(4) One person stated that we should avoid all commercial products listings as they are not updated and that the best lists are on-line at http://forums.delphiforums.com/celiac and http://www.enabling.com

(5) One mentioned a book by Shelley Case but could not remember the name of it--maybe someone else does??

(6) Several said that the guides overlap and that the CSA guide is lots of East coast brands and the Tri-County is lots of West coast brands.

Hope this helps
