Many thanks to commenter OSU Grad Student for pointing me to this Inside Higher Ed item from today:

Ohio State University officials on Friday cleared Scott Savage, a librarian at the Mansfield campus, of harassment charges filed against him based on his recommendation of an anti-gay book for a freshman reading assignment. A conservative group had threatened to sue the university if the charges were not dropped. They were dropped the same day that the group went public with its complaints about the way the librarian was being treated.

Delighted to hear it, and especially pleased that the university acted so quickly.
