Are you _in_ Silicon Valley? I ask because I remember that when I was in Bells Books on Emerson in Palo Alto a month or two ago they had a display of Silicon Valley themed books that I think had a few different coffee table books. I had a chat with the person at the counter about them when he saw me browsing them.
I think the book suggested above was among them, but there were definitely a few more. Some (not all) of them may have been ‘old’ - but I think ‘old’ Silicon Valley books may be what you’re after?
If you’re nearby maybe go and take a look and/or ask the staff members there? (Or maybe someone reading this can and report back here? :-)
