The main reference book on picture mounting for the picture frame industry is "The Mounting and Laminating Handbook" by Chris A. Paschke. This book is mostly available through trade organizations and not easily purchased, especially the newer 3rd edition. For that reason we decided to carry it so that our customers could more easily purchase it. It has everything you ever wanted to know about Dry Mounting and T-hinging and other photo mounting techniques.
Thanks for letting me know Greg...the links are fixed. If you click on the Library button towards the bottom of the left header it takes you to her mounting article archive.
Here is a promo code for Apug'ers to get 15% off the book thru Friday the 9th of Nov: APUGMOUNT
