If you are interested in a list of (vintage) books and articles on electronic music and synthesizers: here is one from 1972. It was published in Studio Sound magazine.
Including books and articles bij Tom Oberheim, Robert Moog and Herbert Deutsch, it gives a good insight in what the status of technology was these days. Quite some of these documents can still be found on the internet or via 2nd hand book shops. Maybe you own some of the items from this list and want to comment on it, or even share it?
