The ticTOCs Journal Table of Contents Service from Joint Information Systems Committee (JISC) provides the Table of Contents from over 11,000 journals for free. Faculty who want assistance in keeping up with new research in their field would appreciate this service. The notification is through RSS only limting the usefulness to those who use RSS. Librarians could email the contents of feeds for those who are less tech saavy as a servie.
Thanks to Richard Ackerman of Science Library Pad for bringing this service to my attention.
