IEEE now has RSS feeds for new journal issues
From SLA's Physics, Astronomy, Mathematics division email list:
As part of yesterday's maintenance release of the IEEE Xplore digital library, RSS feeds for new issues of IEEE journals are now available for all titles.
Feeds are available individually from each journal's main page in IEEE Xplore.
To see one example, visit the Proceedings of the IEEE main page at

RSS feeds can also be found through the Table of Contents Alerts service, which continues to offer notification by email.
