Sitting in Pittsburgh International Airport, getting ready to fly to Pensacola via Atlanta for the week. The plan is to pick up my car, which has inexplicably appeared there instead of Pittsburgh, where I left it, and drive back to the 'Burgh next weekend.

I'll be picking up books while I'm down there. The complete Preacher, Y: The Last Man, 100 Bullets, Lucifer, Fables, Sandman, The Invisibles, that sort of thing. In addition, I may grab a box or two of prose books I've read and am hoarding and open up an eBay store to try to recoup the cost of being a hardcore bibliophile. 
Purchasing prose books seems to be a losing proposition these days. 300 pages of text for $15 isn't exactly a winning equation, as that's only almost 3 hours worth of reading. I demand a higher ratio of cost to entertainment for the media I consume, and a book is a much larger time investment than renting a movie.
The other problem the book industry faces with me is the library. A good library has everything I want to read. Northland and Pittsburgh Public pick up just about every new novel that comes out. I honestly think Northland has a better selection than most of the libraries I looked at in Brooklyn. That leaves me renting movies and borrowing books. The only media I really expend money on anymore are comics and video games.
Comics are kind of a strange beast when it comes to purchases. The market depends on monthly sales, and titles with low monthly sales often don't get collected into trades. As such, I'm inclined to buy singles, but I prefer trades. They contain complete stories and look great on my bookshelf. I am more likely to re-read titles I own in trade than I am titles I own as single issues. I've re-read Sandman and Preacher multiple times. I read each issue of The Walking Dead when it comes out and file it away in a box. Granted, an argument could be made in that example that Sandman and Preacher reward multiple readings while The Walking Dead is pulp-horror, but I'm not making an argument based on content. 
Usually, the only singles I re-read are self-contained in and of themselves. Issues of Fell are frequent revisits for me, because every issue is its own story. Same with this last arc of Criminal. The most curious aspect of comic-collecting, for me, anyhow, is the idea of purchasing collections of runs you already own. For instance, I own all the singles of Criminal, but purchase the trades the day they come out. Often my argument for this has been that I want other people to read these books, and I'm far more likely to get back a trade in good condition than a stack of single issues. Either way, I seem to have no qualms paying double for something, though I'm sometimes receiving less. Criminal and Casanova publish essays and supplemental artwork in their backpages which don't make the transition to the trades. Is this a reward system that encourages me to purchase the singles? If so, it's working.
