With the advent of the Internet, users could share thoughts, ideas, and rants almost instantaneously across oceans, mountain ranges, or even just across a mere ZIP code boundary. With this latest device created by Tim Spalding, those who are so inclined can share information about their own personal libraries across great distances. Currently users can catalog up to 200 books at no charge and also create tags for each record as they do so. Overall, this is a rather fun little tool, and it may become quite addictive over time. Library Thing is compatible with all operating systems.
