I read Brian's "UNIX: A History and a Memoir"[0] last year, which wound up also being an excellent snapshot of the goings-on in Bell Labs around that era. Kicked off a long month of Wikipedia binging. If you want more detail from a guy who was there, it's a good read.
I recommend not buying the print copy though: Amazon prints it themselves on demand and it's far and away the worst quality book I've ever held. The cover is pixellated and skewed, and most of the images inside look like they started life as 50×50px thumbnails.
Edit: apparently the Kindle version is "just the PDF of the paper version"[1] per Brian himself and is thus also terribly formatted. Welp, damned if you do. Still worth a read.
