A Wall Street Journal article about the awesomeness borrowing books from the library for free:
Owning a book is a serious relationship. Once I’ve bought it, as a cheapskate, I feel obligated to read it — even if it turns out to be a dud. By contrast, many books I get from the library go unread. I get a few pages into them and realize I can’t stand the way the author writes. Or the topic simply doesn’t hold me. Back to the library it goes.
