Reddit mentions of Twenty Salmon Flies: Tying Techniques for Mastering the Classic Patterns

Here is a quick list of can't miss books in my opinion:

Michael Radencich as several books out, but this one should be a first if you want to head down this road. He outlines 20 classics and walks you through step by step. If you order from his site directly, he will autograph the book. These books are not cheap but worth their weight in gold:

Mikal Frodin put together an excellent book of classic patterns that include recipes. The really nice thing about this book is that he provides the history of the fly as well. The pictures are not the best and the dressings are not either (at least for display quality as we know it now), but for $10 used hardcover, it's a no brainer.

TE Pryce-Tannatt is one of the last "masters" and depending on the volume you get this book is collectible and gets pricey. This version is not and has a ton of excellent information:
