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. This license is often compared to “copyleft” free and open source software licenses. All new works based on yours will carry the same license, so any derivatives will also allow commercial use. This is the license used by Wikipedia, and is recommended for materials that would benefit from incorporating content from Wikipedia and similarly licensed projects.

Public Domain

Creative Commons also provides tools that work in the “all rights granted” space of the public domain.

 CC0  No Rights Reserved

The CC0 tool  "enables scientists, educators, artists and other creators and owners of copyright- or database-protected content to waive those interests in their works and thereby place them as completely as possible in the public domain, so that others may freely build upon, enhance and reuse the works for any purposes without restriction under copyright or database."

PDM  No Known Copyright

The Public Domain Mark  " enables works that are no longer restricted by copyright to be marked as such in a standard and simple way, making them easily discoverable and available to others."
