If you’re interested in learning to bind books, the best place to start (IMO) would be YouTube tutorials! Here’s who I would recommend:
DAS Bookbinding has a lot of great info and projects, a lot of which are historical bindings. Here’s his playlist for getting started, and here’s his playlist for a rounded & backed cased book.
Sea Lemon is another popular YouTuber, and her bookbindings are a bit more casual. Here’s her playlist on methods & stitches, and here’s her playlist on supplies & tips.
Good luck!
Just getting started myself, cannot recommend DAS Bookbinding enough. i’ve learned so much in a very short period of time that has helped me immensely.
