Here’s a recently released guidebook that was developed by the OAPEN-UK team (Ellen Collins, Caren Milloy and Graham Stone) and edited by James Baker, Martin Paul Eve and Ernesto Priego.
It runs 32 pages.
From the Guide:
This guide explores concerns expressed in public evidence given by researchers, learned societies and publishers to inquiries in the House of Commons and the House of Lords, and also concerns expressed by researchers working with the OAPEN-UK project. We have also identified a number of common questions and have drafted answers, which have been checked by experts including Creative Commons. The guide has been edited by active researchers, to make sure that it is relevant and useful to academics faced with making decisions about publishing.
[Our emphasis] This guide is specifically about Creative Commons licences, not about open access in general.
