I do own a lot of books but that doesn't stop me from making frequent visits to my local library. Frankly, the library prevents me from living in a cardboard box with all of the books I would have to own if there were no such thing as public libraries. I'm probably there about once every other week, sometimes more. My library is only a little over a mile away from where I live so it's a nice short walk. I've been really impressed with my city's public library system. I have come across very few books that I'm not able to get at the library. If I find a book I want at another branch, I simply put in a request online and the book is magically transported to my local library. It's like having a personal bookstore where everything is free!
I understand there are others out there who do not have such a profound love for libraries. This article may be appropriate for you. Maybe you'll see the light ;)
Where do you usually get your books? Library or buy?
