I was interested to see the following on the Amazon Web Services blog:
Concord USA has developed and released, free-of-charge, an Amazon course item module for colleges and schools that use the learning management system from Blackboard Inc. This module allows course developers to include books and other items from amazon.com in their Blackboard online courses.[Amazon Web Services Blog: Blackboard Learning Management System]
To note: the institution can collect a referral fee when students click through and purchase items.
