"A number of the enquiries to the Open Access Enquiries mailing list have asked us how the various types of Creative Commons licence specifically relate to scholarly articles. So, in this blog post we explain the rights that the CC BY licence grants to the reader (i.e. the licensee).
The RCUK policy currently mandates use of the Creative Commons ‘Attribution’ licence (CC BY) when an Article Processing Charge (APC) is levied. This licence allows others to distribute, remix, tweak, and build upon the licensed work, including for commercial purposes, as long as the original author is credited. It is the most liberal of the six Creative Commons licences in comparison with, for example, CC BY-ND (no derivatives, no modifications) and CC BY-NC (no commercial use)."
