<human>: I've got 900 movies and 1,000+ books. While I have a good enough memory to remember "most" of them, I sometimes find myself buying duplicates when good deals happen at Best Buy or Suncoast. Shit gets confusing when I have about 600-700 in the movie cases, and the rest in a DVD binder. I'm hoping to get a list of it that can be easily carried and updated (electronic solution compared to paper). I've got an iPhone, and tried using a list in my email, the in-built notes app, and RedLaser - but none are quite what I'm looking for. 

^ Same issue with my books (four bookshelves, and a box in my computer room that needs a shelf somewhere in the house).

I want a alphabetic-capable search maybe?

Can you condense the text into three sentences or less?
<bot>: I'd like to categorize my 900+ movies/tv shows and 1,000+ books electrionically. I have an iPhone. Any suggestions?
