On a site of a new colleague I stumbled upon this: SSOAR – Social Science Open Access Repository. Basically it is a database with freely available document, mainly from the social sciences but also open for other fields of science. The site is nicely designed and is focused on what it is meant to be: upload documents and browse by categories and keywords through the different documents. I would really like to recommend the page and it is not necessary to write more on it, its usability stands for itself.
