Use Blackboard when you need to share material with your students. Do not use Dropbox, Facebook, e-mails, etc., to share copyright-protected material.
The Copyright Act does not allow you to simply share material without restriction. However, if you share via a secure closed network such as Blackboard, you may, as a lecturer, take advantage of the agreements that Aarhus University and Aarhus University Library has entered into with rights holders:
None of the agreements allow you to simply upload anything to Blackboard, but they do considerably improve your ability to share material legally. You are permitted to leave the material on the course portal when the semester is over.
See a sample Reading List that takes the copyright rules into account.

If you produce video material yourself, please use Kaltura as a publishing platform rather than YouTube or Vimeo. Kaltura is fully integrated into Blackboard, and offers a number of copyright advantages - read more under Video.
