Taxonomic notification System

[Susan B. Farmer]

It's not exactly a subscription service, but isn't the Kew Record of
Taxonomic Literature (http://www.rbgkew.org.uk/bibliographies/KR//KRHomeExt.html)
similar to what you're talking about?  Granted, it's just plant literature --
but I check it regularly.
