How Does Your Team Learn about Mechanisms?

A team asked me how to learn more about mechanical motions the other day and I like to recommend two sources. I am sure there are others out there, so please recommend your favorite by adding a comment.

1. Amazon.com - 1800 Mechanical Movements, Devices and Appliances
   
2. http://kmoddl.library.cornell.edu/ - Kinematic Models for Design Digital Library
