Happy Telephone Day! Given the ubiquity of telephones in today's society, it can be hard to believe we ever survived without them. Amazingly, it's been less than 150 years since Alexander Graham Bell patented his telephone invention. While others also lay claim to the birth of this revolutionary device, the telephone, even as Bell knew it, has gone through innumerable changes since it first appeared in 1876. It's doubtful that he ever imagined a device that could call, send messages and letters, store tons of files, photos, and other information, and still fit in a pocket or a purse. While all those bells and whistles are fun and revolutionary, libraries have found unique ways to harness the power of a simple phone call in the service of literacy and information.
