Open licenses

Licenses are a way of giving permission to someone to use your work in a certain way. (When you hear "license," think "permission.") You've probably seen Creative Commons licenses in educational settings. Similar to open source software licenses, they allow the creator (or rights holder, if copyright has been transferred) of an educational or scholarly work to retain their copyright while granting users permission to use their work in certain ways. All the creator needs to do is share the license on the work itself.

Depending on the license chosen by the creator, users may be allowed to:

Retain - make, own, and control a copy of the resource (e.g., download and keep your own copy)
Revise - edit, adapt, and modify your copy of the resource (e.g., translate into another language)
Remix - combine your original or revised copy of the resource with other existing material to create something new (e.g., make a mashup)
Reuse - use your original, revised, or remixed copy of the resource publicly (e.g., on a website, in a presentation, in a class)
Redistribute - share copies of your original, revised, or remixed copy of the resource with others (e.g., post a copy online or give one to a friend)

Open licenses are less restrictive than "all rights reserved" copyright, where a creator does not specify any type of license, but more restrictive than works in the public domain, where copyright has expired, or where a rights holder has waived all rights to their work.

Types of Creative Commons Licenses

CC0 Public Domain Dedication Attribution
Using CC0 waives all copyright and related rights to a work to the extent possible under the law.
Attribution, CC BY
This is the most open of all licenses offered. Allows others to distribute, remix, tweak, and build upon your work, even commercially, as long as they credit you for the original creation.
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.
Attribution-NoDerivatives, 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.
Attribution-NonCommercial, CC BY-NC
This license lets others remix, tweak, and build upon your work non-commercially, and although their new works must also acknowledge you and be non-commercial, they don’t have to license their derivative works on the same terms.
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.
Attribution-NonCommercial-NoDerivs, CC BY-NC-ND
This license is the most restrictive of the 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.

Creative Commons

Creative Commons (CC) helps you share your knowledge & creativity with the world by marking your work as "open access."

Simply choose which license you prefer and mark your work which license you've chosen.
