Open access refers to a set of principles and practices for distributing research outputs online, free of charge and without restrictions while the author retains copyright of their work.
To ensure that others can access, copy, and use research freely, articles are published under a Creative Commons license however the author must be correctly credited as the source.
These are all electronic resources that are made available on the internet including YouTube videos. TED and YouTube films or videos are openly available to all users therefore a lecturer may share a link with students for educational purposes in their original online format. However, they may only be downloaded if they are free or open access resources, or if prior copyright permission has been obtained.
Creative Commons is a non-profit organization that provides standardized ways to give the public permission to share and use creative work on conditions of the authors choice. This simply changes the copyright terms from the default of “all rights reserved” to “some rights reserved".
There are six different license types that authors can chose from depending on what restrictions they prefer.
