The MLA has started a new initiative, named the Humanities Commons. According to the Commons’s introductory webinar registration page,
Imagine a humanities network with the sharing power of Academia.edu, the archival quality of an institutional repository, and a commitment to using and contributing to open source software. Now imagine that this network is not-for-profit. It doesn’t want to sell your data or generate profit from your intellectual property. That’s Humanities Commons. Run by a nonprofit consortium of scholarly societies, Humanities Commons wants to help you curate your online presence, expand the reach of your scholarship—whatever form it may take—and connect with other scholars who share your interests.
For more information, view the webinar or peruse the Commons’s website.
