Reddit mentions of The Real Book - Volume I: C Edition

The lack of electronics is a little annoying. Usually I would recommend doing a lot of transcription. Once you learn the basics, the best thing to do is jump right in and get first hand experience. Will you have any way to listen to music? If not, definitely pick up some books of transcribed solos from your favorite guitarists. You would be missing out on the ear training you get from transcribing and it would be harder to memorize licks, but you would get some good sight reading practice at least. It might also be good to pick up some transcribed bass lines if you can find a book of those, because looking at bass lines is a great way to get a feel for jazz harmony. And bring The Real Book, of course! You'll have plenty of time to memorize tunes, which is going to be extremely important in the future.

For jazz, get the Real Book. Start with the first one. I've got the first three volumes, but there are more.
