I worked in bookstores to help put myself through college, and would quickly become known as the person to send customers to who were asking for those weirdo books on sed and awk or lex and yacc. Even as recently as 2002-2005, though, some bookstores and computer shops still had excellent selections on some pretty obscure topics. Some of the guys who worked at the college back in the early 90s, though, and who had been there since the 50s and 60s -- analog radio and broadcast engineers -- man, those guys were walking encyclopedias. It was great to hear their stories of how the college radio station was first set up, in 1960, and how things were back then. I always felt as if I had missed a really important time in our nation's history.
