There is a very succinct new page on why, how and where you, as a philosopher, can publish your texts in open access. It is mainly about self-archiving and why you should do it on a repository rather than on your homepage or on academia.edu or even philpapers.
One thing I didn’t know is that except for Mind all other journals in philosophy allow for your archiving in open access at most 12 months after publication. In Mind it’s after 24 months. And all journals in philosophy allow you to place a preprint on our institutional server (rerodoc) where your ideas are protected against plagiarism, since your preprint placement provides proof of date.
Here ist the page: http://von-wachter.de/oa-en.htm
(Thanks to Thomas Henkel for indicating the page to me.)
