Specifically, I'd get my hand on the Radencich book listed above. Still,
this book has a lot of character, and gives you a good feel for the
history of the art. Nine color plates and lots of pen and ink
drawings.
Make sure you note that this book was produced in 1914, well before
anyone was using fly tying vises. A lot of the instructions give careful
direction on how to hold thread with one hand while winding with the
other, etc. For example, you can see how to tie on the silk eye here.
If you are interested in this book, or the Frodin or some of the
other older ones, you might try Ken Callahan of Callahan and Company
Books, in Sharon, NH (603-924-3726). Ken has a wonderful library of
pre-owned hunting, fishing and general sporting books and publishes a
monthly catalog.
