I'm really "organized": I have this book shelf, you see, and on the top shelf, Ihave a collection of DVD's, but here's how they're organzied: I have any season and or volumes sets first, in order of which I got the first season or volume. Like, first I have seasons 1-3 of Rocky and Bullwinkle, seasons 1-3 of Green Acres, two volumes of Andy Griffith, two volumes of Ed, Edd n Eddy, two seasons of Bewitched, make-shift volume sets I make of footage of my puppet during our PBS Kids pledge drive, two make-shift season sets of Courage the Cowadly Dog (I'm working on season 3 right now), season 1 of The Muppet Show, and (hopefully) seasons 1-7 of M*A*S*H, and make-shift season 8 with the Radar episodes. After those, I have just regular movies and films on DVD, in order of which I got them.
On my bottom shelf are my books and magazines, and again, in the same order (from whAT i fIRST gOT, TO the last book I got, with volume sets, or multiple issues of magazines, or yearbooks at the beginning).
On top of the book case I have a little cardboard box filled with comic books with newer issues on the bottom.
