Springer and MIT have reached an agreement that will result in Springer automatically depositing MIT-authored papers in DSpace@MIT nine months after publication.
Here's an excerpt from the announcement:
The MIT Faculty Open Access Policy, one of the first initiatives of its kind in the United States, made a bold commitment to disseminate the results of MIT research and scholarship as widely and openly as possible. Recently, the MIT Libraries affirmed this commitment by signing an innovative agreement with Springer, one of the world's largest scholarly publishers. Springer will send manuscripts of MIT-authored scholarly papers directly to the Open Access Articles Collection of DSpace@MIT, the Institute's open access repository.
