What's New in MathSciNet: RSS feeds for Journals
I haven't seen anyone else mention this...
What's New in MathSciNet: "Current awareness of journals using RSS
For those using RSS feeds for current awareness, RSS 1.0 and RSS 2.0 links are provided on the bibliographic information page for each journal covered by MathSciNet. These links will provide updated information about a journal issue as soon as that issue is loaded in MathSciNet."
