To follow this drift re Graves' Greek Myths:— It is not so much a book on the myths as an idiosyncratic but coherent retelling of them in sequence — Titans-Olympians-House·of·Atreus &c, superbly indexed: thus providing an invaluable ref'ce tool. When I come across a name from myth I can't quite place or remember, 5 minutes with Graves will bring it back to me [or, if one I haven't come across before, fill me in on it], placing it in the context of the myth-canon as a whole.
