Licensing is important because it allows creators keep their ownership yet at the same time defining under which conditions their work can be openly used.
Attribution-ShareAlike CC BY-SA This license lets others remix, tweak, and build upon your work even for commercial purposes, as long as they credit you and license their new creations under the identical terms. View License Deed | View Legal Code
Attribution-NoDerivs CC BY-ND This license allows for redistribution, commercial and non-commercial, as long as it is passed along unchanged and in whole, with credit to you. View License Deed | View Legal Code
CC0 1.0 Universal CC0 Also know as Creative Commons Zero, this licensing tool lets others distribute, remix, tweak, and build upon your work, even commercially, without a need for attribution. Creative Commons developed this tool to work in the “all rights granted” space of the public domain. The CC0 tool allows licensors to waive all rights and place a work in the public domain, and the Public Domain Mark allows any web user to “mark” a work as being in the public domain. Unlike other Creative Commons licence terms these works do not require attribution (although attribution is always appreciated). View License Deed | View Legal Code
Attribution-NonCommercial-ShareAlike CC BY-NC-SA This license lets others remix, tweak, and build upon your work non-commercially, as long as they credit you and license their new creations under the identical terms. View License Deed | View Legal Code
Attribution-NonCommercial-NoDerivs CC BY-NC-ND This license is the most restrictive of our six main licenses, only allowing others to download your works and share them with others as long as they credit you, but they can’t change them in any way or use them commercially.

Many open education advocates prefer CC-BY licences because they offer the most flexible options for others to reuse OER work. The CC-BY Creative Commons licence is also known as the “CC Attribution licence”. Creative Commons explains the licence in the following way:
You are free to:
Under the following terms:
CC-BY is the most open of the Creative Commons licenses, which means that society at large can build upon content licensed this way in the easiest, freest and most effective ways. Licensing this way builds on an open information ecosystem, where not only can any student get access to textbooks for free, but further, anyone — another professor, a university, an app maker, or an artist — can build new value, new content and new services on top of this base layer of “public good,” the Open Educational Resource. This is exciting!
Other Creative Commons licences (namely no-derivatives, non-commercial and share-alike) place limitations on how Open Textbooks and OER in education can be reused. In particular:
In theory, yes, anyone can do anything they want with CC-BY-licenced work as long as they provide attribution to its creators.
The attribution requirement is a deterrent for anyone looking to profit from your work, especially if you clearly set out how you expect to be attributed. If the attribution makes it clear to a potential buyer that they can find the content elsewhere for free, there is little interest for a commercial publisher to invest in creating a paid version.
Some authors use the NC licence attribute to stop their content from being used as a part of a paid service, or a service offered by a for-profit company, but it is not clear that this restricts all commercial uses of the material. More restrictive again is using a CC BY-NC-SA licence which means that the entity reusing the material must share the work under a similar licence which can further inhibit commercialization.
