Well, this is certainly the most comprehensive treatise I have ever seen on Open Access publishing: Open Access Publishing: A Literature Review | CREATe. It was written by “Giancarlo Frosio under the supervision of Estelle Derclaye (2014)” and
comes from the Centre for Copyright and New Business Models in the Creative Economy (CREATe). It is VERY comprehensive and has discussion, review, and comments on just about every issue associated with Open Access publishing that one could think of. I do not know if there is any particular “angle” to the writings here. What I looked at (not all of the document) seemed to be a relatively objective assessment of various OA issues. Anyway, it is definitely worth a look for anyone interested in scholarly publishing or Open Access publishing or related issues.
