As useful as sites like these are, there is still no substitute for the encyclopedic Ashley Book of Knots[1][2], which contains every knot under the sun and then some (up to the time it was written -- and, to be fair, quite a few knots have been invented since then, but it's still an impressive tome).
I have mixed feelings about Ashley - there's no doubt it's a very cool book for its sweeping scope, but I would never recommend it as a guide for learning tie knots. There are many good choices from Budworth[1], Pawson[2], Toss[3] and more.
