I was wondering what you would consider important knitting books for a permanent collection at a public library. I want to come up with a list diverse in subject matter (beginner's, advanced, technique, patterns, stitch dictionary, design, ethnic etc.), as well as a relatively timeless list which avoids trends as our library is not particularly well funded. The current collection's downfall is that it contains books which are not very well written, books of patterns/projects which are outdated/just plain corny, and not much in the way of technical information. Any suggestions would be much appreciated.
