We bought this book to read up about houserabbits before we took on two rabbits from a rabbit rescue. We still refer to it a lot when we have a query, and it very often helps.
It has lots of tips on the whole process, from thinking about getting a rabbit, to how to prepare your home if you would like your rabbit to live inside, to what rabbits eat, how they behave, and what you need to do to look after them properly. It has lots of great pictures too. It is well organised into logical chapters, and is full of practical tips.
