When I read your query, I checked on Google using the word "knots". I
was surprised to find the first site listed was titled "Knots on the
Web", a 35 page compilation of books, videos, et al - certainly the most
complete reference I can imagine.
The most interesting thing to me, however, was that this listing had
been compiled by Peter Suber in the Department of Philosophy at Earlham
College in Richmond, Indiana - astonishing because one of my daughters
graduated from Earlham ~25 years ago, at that time a small but great
college. (One of the professors suggested she apply to teach English at
a Japanese school which had a relationship with Earlham, so she did and
taught in Utsonomya for 3 years. She now teaches Japanese at a Seattle
High School, and has been back to Japan with some of her students on a
couple of occasions.
Anyway, this reference is one that should answer all of the questions
you ever thought about with knots.
