IPL: The Internet Public Library I know I have this linked elsewhere, but it bears repeating....

Literally. Make sure your telnet utility is linked in to your Web browser. Find that hard-to-find book and then get your local library to order it....Parts of this list are from the Internet Librarian column by Karen Schneider in American Libraries.
