Many books, too many to mention contain personal emblems dotted around in them. I'm pretty sure there is not a dedicated personal emblem book. You could try some of the Classic Colours Jagdwaffe titles. Luftwaffe emblemes by Karl Ries has a few also the 4 volume emblem and markings books again by Karl Reis. All these titles are pretty expensive though and that's if you can track them down. Dependant on what you need them for it would probably work out a cheaper to search around on the net. Or maybe even start a new topic asking members if they would be kind enough to post the ones hey know of?
