I'd say "The Internet", in general. Doesn't matter who the author is, but there are thousands of free websites and e-books available on the whole
wide range of paranormal/esoteric subjects.
Better not to get attached to certain authors and give them a following.
If for some weird reason you insist on buying a book, or subscribing to the ideas of a specific author, I'd say:
Robert A. Monroe. (Astral Projection topics only)
Books: Journeys Out of The Body, Far Journeys, Ultimate Journey
Samael Aun Weor (and don't even buy the books, because free e-books are available all over the internet.) (More spiritual/philosophical in his
approach. Lucid dreaming, astral projection, tons of other topics.)
Books: (Dozens). I'd say The Great Rebellion and The Three Mountains are a good start.
