I have, for the most part, an addictive personality. If there's something I'm into, I become addicted to it.... basically. And I've lost count of all the things I've become addicted to over the years. Chocolate, stealing, stickers, medal games...
Fanbooks are no different. It was really bad a couple of years ago, when I would go to events, buy anything that caught my fancy, then stack it somewhere and forget all about it. I know I don't have to largest collection, no more than 500, I'm sure, but they're collecting dust, and I really shouldn't buy another book until I go through the ones I have already.
Especially since I've found a couple of duplicates in my collection. Fuck.
I mostly have Harry Potter, Gintama, and Hetalia books, but I do have few oddballs here. Let's check them out before I chuck/sell them.
