Okay, had a moment to rummage some book shelves: here's 3, 2 are classics, one is so chock full of patterns I just sit and read it sometimes (sorta like reading interesting encyclopedia entries, or taking one link to another on the web!!!)
The Weaving Book: Nearly 3000 variations of Plain Weave, Overshot, Twill, Monk's Belt, and Huck Weaves. Helene Bress, 1981, Scribners (the last mentioned above)
A Handweaver's Pattern Book, Self-published first in the 1940's, reissued many times, my edition is 1996. By Marguerite Porter Davison. Very famous, just google her: I am sure something will come up. A staple in larger, very good libraries.
New Key to Weaving, Mary E. Black. MacMillan publisher. A Classic, classic, sure to be found in libraries, on-line and even book stores. (Try Amazon, used one's come up all the time.)
Hope some of these can be of use to you--I'm very partial to the Bress book. Clear, concise yet dense, with a sense of humor!
