WorldCat.Org

I found a link to WorldCat.Org via SF Signal and it's a tool to help locate books at local libraries, although I am honestly still baffled by the user interface (and whether it applies to the Philippines--any librarians contributed to this endeavor?). Here's the services it theoretically can provide:

• Search many libraries at once for an item and then locate it in a library nearby
• Find books, music, and videos to check out
• Find research articles and digital items (like audiobooks) that can be directly viewed or downloaded
• Link to "Ask a Librarian" and other services at your library
• Post your review of an item, or contribute factual information about it
