I find the best recommendations to be the works cited in other works you like. You can press pause in a movie when the camera goes over the bed side table book, or write down the movie they go see in the book you read. Gives a growing list to discuss with your librarian, although some time you need to branch out. Nice idea that’s mentioned there, shame it is only for non fiction books, would be interested in a fiction equivalent!

Well, it sometimes happens if you read about the bool, e.g. Pynchon's V put me onto Heart of Darkness
