I'd also like to express my thanks to LXF for the free books, which were awaiting my return from vacation.
"SQL Cookbook" is probably the most useful for me... I intend to do some stuff with MySQL later in the year (using the "Dummies" book as my starting point) and an alternative reference book is always a bonus.
"Pro Perl" is interesting. No intention of learning Perl at the moment, but you never know... It looks like a pretty complete guide.
I'm sure I'll find a use for "Teach Yourself Fedora 4"... probably as a donation to the next person who asks me about getting into Linux
