Two more things that I forgot to mention about backing up your computer to DVD

Pick up some CD/DVD sleeves, they might be in the same aisle as the DVDs. You can get a box of 50 of them for pretty cheap. Also get a medium-point Sharpie marker to write date and basic content info onto the DVDs. Don't bother with printing labels and sticking them on, theoretically you won't be pulling these out on a regular basis to load things from them and the additional cost and labor just isn't worth it.

The religious affiliations of comic-book superheroes

It even breaks down as to who has met God and which ones are GLBT. Interesting stuff, something I'm going to have to look at more closely. I only wish they'd alphabetized the lists.
