It is a requirement of the publishing and book business that if you are
going to put a product on the shelf you need a price and other bits of
info. Even if a book was never sold, some manufacturers always put the
extra on the book just in case. and sometimes I'm sure it was the
contractor who did the book for the chip people who routinely did that
on their product as well.
Reps were always the best ones to get to, followed by a distributor from
who you purchased a reasonable amount of product. Hamilton was always
nice as was Avnet before they merged. They would let you go into their
library and just load up here in Irvine. Sometimes they would ask
questions because they wanted to track the projects at your company, and
if you were loading up on weird stuff you'd tell them it was for your
own research.
