Some good suggestions here, along with books that are too dated or too modest in size to be of much use.
I'd recommend the Sissy Haas book, as a very useful overview with some notes on aspects of doubles and observing them. It's arranged by constellation, which I find more practical than purely by RA - which, with a pole to pole guide, gives you doubles at -60 and +60 Dec side by side - one will be in view, the other accessible only from the other Hemisphere (depends on you living which side of the Equator). The Haas book is not as good as could be for the quicker binaries, but most of those are very close pairs, so it's not a big deal for most. It is an excellent listing with basic data and observational notes on most of the brighter and more interesting doubles across the whole sky, North Pole to South Pole.
The Cambridge Double Star Atlas is useful for quick locating of pairs on a map, with some notes on them in the latter part of the book. Two Editions - the first had information already out of date for too many pairs, and a sub-optimal choice, missing some good'uns and including some of little interest. However the introductory material on doubles and observing was good.
The Second Edition included various good doubles that were previously missed, but foolishly tried to leave out optical doubles. That's fine for astrophysics - but not for an observing manual. Various outstanding optical pairs were lost, such as h 4945 in Canis Major. A further problem is that we don't always know which pairs are merely optical, so some exclusions were based on assumptions. As well, the introductory materials are a mix of the standard and the idiosyncratic, hence could be misleading for the newbies.
So both editions have their virtues, and their deficiencies. I have both, use them for the maps, which are the usual excellence by Wil Tirion, but wish the choice of stars in each had been done better.
For more detailed material on doubles and observing, Bob Argyle's Observing and Measuring Visual Double Stars (preferably 2nd Edition) is excellent.
