Reddit mentions of On the Safe Edge: A Manual for SM Play

They have a few books out, which are not bad. They do workshops, too. They're mostly geared toward western-style, 50's era cotton rope aesthetic bondage(as opposed to japanese bondage which actually has little to zero true knots) and maybe more soft-core players, or at least entry level, but you can learn a lot from them and expand with a bit of creativity.

Personally, I'm looking forward to eventually getting this collection of books for myself - they're some of the most comprehensive available, from what I understand.

Also, for safety, I do have this book and appreciate it as a solid primer for understanding some health and safety issues in kinky play. The rope section is the most relevant to me, but the rest is interesting reading. Funny enough, I bought the book after I caused temporary nerve damage to a friend's hand from doing a tie described in a book written by Mistress Midori... I had gone on the stockroom.com forums to ask for advice on where to find such a book and who was the one to respond to my request? Midori herself. Even now, I believe it was fault of the tie design, not my miss-handling. Irony.

Fappy playing! :)

It doesn't seem like you've talked to him enough about it. Why doesn't he like it? You might not have made him understand why you like it. "Vanilla" people tend to see just the pain involved. They don't want to inflict pain on someone they love and don't understand why someone would want to be hurt on purpose. So you'll need to explain that and/or maybe get him a book about BDSM. A decent all-purpose book I have is: http://www.amazon.com/On-Safe-Edge-Manual-Play/dp/1895857058 This looks good and is well reviewed too though I haven't read it: http://www.amazon.com/SM-101-A-Realistic-Introduction/dp/0963976389/ref=pd_sim_b_3
