My 13 month old is the same. I don't have any good book recommendations, but my best strategy is keeping things he shouldn't have out of sight/away. Like, bathroom door always closed so he won't drop things in the toilet, cat food behind a baby gate so he won't eat it, all electronic equipment up high, etc. I try to limit the amount of things I have to say "No" to. When I do accidentally leave something within his grasp I mostly distract him with something else while I remove the first thing. He'll get it eventually.
