B.H. Breslauer Foundation for rare books and manuscripts

The B.H. BreslauerFoundation gives grants to libraries and nfp's that collect rare books and manuscripts. 

Applications for grants to make specific acquisitions can be made by correspondence, e-mail, or telephone. They should be accompanied by as much relevant documentation as possible on the desired acquisition, as well as precise information on provenance and price. Because of the nature of the rare book market and the auction process, the officers of the foundation generally make the effort to respond promptly. 

There's no deadline, this is an ongoing program.
