Wouldn't that make you a bigamist?

Did I mention I have the Movie Trade Paperback, the illustrated edition (big silver dust jacketed book), the illustrated 25th anniversary edition, the Harmony Books Hitchhiker's Quartet (when it was just 4 books), the Leather bound collector's volume (after Mostly Harmless), Mostly harmless in a standalone hardback, the UK Editions of Salmon of Doubt and the 2nd edition of Don't Panic, both Dirk Gently books, Last Chance to see, the Meaning of Liff and Deeper Meaning of Liff, the DC comics version of H2G2 and REU....
German editions of the 5 Hitchhiker's books, both Dirk Gently novels, Don't Panic and Last Chance to See.
The now long out of print Last Chance to See CD-ROMs, the UK/Region 2 release of the DVDs, all 18 (to date) radio episodes plus bonus CDs AND "Douglas Adams at the BBC." And most recently the US edition of Wish you were Here, since someone didn't return my UK edition of Nick Webb's biography of DNA, and ALL of the iTunes tracks (thank you Pepsi for the freebies!)

Obsessed? nah.
