When I was faced with an elaborate bookbinding project in art school, I tracked down Talas. Not only did they have every single thing that I needed (and then some), but the staff was extremely patient and helpful. I was able to buy a range of papers (which they expertly rolled for me in a subway-proof tube), needles, adhesives, and tools -- they had it all. They cater to pros but also have kits for non-specialists. All in all, a great find and art resource.
