SSRN Considered Harmful
The Social Science Research Network (SSRN) has adopted several unfortunate policies that impair open access to scholarship. It should enable one-click download, stop requiring papers to bear SSRN watermarks, and allow authors to point readers to other download sites. If it does not reform, those who are serious about open access should not use SSRN.
