The last thread garnered 22 submissions, so I thought with fall approaching, it would make sense to open a new thread. The rules, as before:

In light of the growing number of these volumes, I am going to run a thread periodically in which I invite authors or readers to share links to philosophical works that are currently or permanently “open access.”  Please use your full name and a valid email address (the latter will not appear) and include the URL for the book (give the title and the author, if you are not the author).  Authors or readers can only say something about the work and what it tries to do.  Please indicate if the “open access” period is limited.

Submit your comment only once, it may take awhile to appear.  Do not post about books that have appeared in earlier iterations of these threads.
