Worldcat.com !

I just chanced upon this really helpful website http://worldcat.org/ .
If you are in US and an avid reader , then I guess this is where you should head to.

It has a very friendly search that can tell you which library in the US has the book that you wish to read.Actually, if you key in your Zip code, then it would list out the libraries that has this book in the increasing of order of distance from your home . Simple, yet powerful idea.

And yep,it can of course search for videos, music , articles or anything that you find in a typical library.Better, it can actually take you to the library page and tell you whether the stuff is on the shelves or checked out.

Don't know for sure how long it has been around or how popular it is, but yep, sharing the info for the benefit of people who haven't heard about it.Happy reading & happy new year @!
