in thread Is Programming Perl still relevant as a reference book?
Check out good computer stores. We have a local Micro Center that has many older editions for $2 to $5 in a clearance section. I have bought many books that way because I never know what I'll need in the future for reference.
Another good source are places like half.com to buy used and new books at a discount.
