The Silva Method programs teach a form of self-hypnosis as do the Genius Code and Photoreading. It depends on what your definition of "hypnosis" is. NLP Practitioners generally have a very broad definition of hypnosis. For a good book on hypnosis read "Traning Trances" by John Overdorf and Julia Silverthorn. "Trance-Formations" by Richard Bandler and John Grinder would be a good choice if you can find a copy at a reasonable price. "Through the Open Door" by Kevin Hogan has a more conventional approach to self-hypnosis.
