Well, my mainstay of books are probably my 108 volumes of Perry Rhodan silver-cover issues, which are collections of the weekly novels - which are currently at issue #2541; yes, it's probably the world's most successful science fiction book series ever...
Then there's a lot (but not all) of Terry Pratchett's books, some novels by Greg Bear, William Gibson and Neal Stephenson (still haven't started reading Cryptonomicon - do I have to hand in my geek card now?). I've also read (and enjoyed) the first nine "Southern Vampire Mysteries" (aka "True Blood") books by Charlaine Harris and am waiting for the tenth to be released...
There's print versions of a few webcomics: Wapsi Square, Girls With Slingshots, Beaver & Steve, The Laugh-Out-Loud Cats and Simon's Cat (okay, not a webcomic...).
And to top it all off, there's oodles of manga: all 40 volumes of 3x3 Eyes, Fullmetal Alchemist, Tenjo Tenge, Battle Angel Alita/BAA Last Order, most of Masamune Shirow's works, Gunsmith Cats, Hyper Police (highly recommended), Hellsing, Gunslinger Girl, Mahoromatic, Read Or Die, Chobits, ...
That's where the DVDs start coming in and making the space on my shelves less and less by the week...
