Interesting book on electronic music

It wasn't cheap decades ago, either. I recall looking around for it about 20 years back, and it was psychotically expensive even then...$200+-ish. I can understand why, as well...besides Electronotes, it's an incredible compendium of electronic music circuits. But it's also an incredible compendium of electronic music circuits that's been out of print since the late 1970s, if I remember right. I do remember thumbing through it during my undergrad studies (my comp/theory prof had a copy) and seeing the bewildering array of possibilities it posed.

The thing that's mystified me, though, is that a book that's clearly so useful has remained virtually unobtainable in the present day. Strange himself died back in 2008, so any effort to republish would have to go through his estate at this point, but that doesn't explain why such a vital text went without a new edition or reprinting between its last date of publication and 2008. I've always wondered if there hadn't been some copyright BS between him and some of the circuit designers (Don Buchla, f'rinstance; there's some of his designs in there, and Don could be notoriously litigious) that's been the sticky point all that time.
