In my hometown I've seen about half of the used book stores disappear within the last 10 years. There are a few still hanging on, but with rising rents and fewer people reading it seems like their days are also numbered. Which is a shame because to me aimlessly perusing through old stacks of books is very enjoyable and somehow comforting. I love the rush you get when you come across some rare book you've spent years looking for, or when you find some new book you didn't know you wanted. Going on Amazon and ordering the exact book you want is easy and convenient, but I don't think it can replicate that feeling of discovery.
