matzleeach, from what perspective?
As far as its accuracy as a theory and how many patterns are necessary for varying levels of play, there are many scientific white papers discussing this:

As far as practical methods, check out Chessimo, De La Maza's book Rapid Chess Improvement, the Leitner System, or Supermemo. These each suggest schedules for spaced repetition (review) that reduce the amount of time it takes to learn.
As far as sources for patterns, most chess books and software. :)
Is there any book that focus on pattern recognition
