Lambda the Ultimate

From Matt Blaze's Shaking Down Science blog post, a letter from the U.Penn. library to faculty:

I am writing to bring to your attention a recent change in IEEE's policy for archiving personal papers within institutional repositories. IEEE altered their policy in January from allowing published versions of articles to be saved in repositories, like ScholarlyCommons, to only allowing pre-published versions. We received no prior notice about this change.

As a result, if you or your students/colleagues publish with IEEE and submit papers to ScholarlyCommons, I am writing to ask that you PLEASE REFRAIN FROM UPLOADING ANY NEW PUBLISHED VERSIONS OF ARTICLES. It is unclear yet whether IEEE material uploaded prior to January already within ScholarlyCommons will need to be removed. Anything new added at this point, however, would be in violation of their new policy.

I.e., the IEEE journals go from being green (allow authors to distribute as-published versions) to pale green (author's may only distribute preprints).
