Do you own books and never read them?

I have boxes of books I never read.  Perhaps it is bibliomania.

I've got 11 fiction in the bookcase I either haven't read or only partly:
American Spendor - Harvey Pekar: got this a birthday or christmas years ago :\
Don Quixote - Cervantes: got to page 732
short story collection vol 4 - Philip K. Dick: read parts
The Pickwick Papers - Charles Dickens: wanted to start on Dickens, went with wrong book, very low brow of me :(
The Great Dune Trilogy - Frank Herbert: read Dune but not the second and third part, I've heard the quality drops afte the first three books and then then 2 and 3 aren't as good either
The Complete Chronicles of Conan - Robert E. Howard: read parts
Les Miserabes - Victor Hugo
The Garden Party (and other stories) - Katherine Mansfield: had this for Year 11 literature, didn't read it then and six years later still haven't
Tales of Mystery and Imagination - Edgar Allan Poe
Red Mars - Kim Stanley Robinson: been putting this off for years
Tierra del Fuego - Jennifer Strauss: same as Garden Party
meanwhile in the non-fiction:
The Crimes of Patriots - Jonathan Kwitny
Out of Control - Leslie Cockburn
Bad Samaritans - Ha-joon Chang
Discovering Orson Welles - Jonathan Rosenbaum
