Thanks to the Shifted Librarian for sharing some slides of ProQuest’s forthcoming keyword RSS feeds. Soon, in addition to email, you will be able to choose RSS delivery of new documents matching your search terms in the ProQuest databases to which your library subscribes.
I, too, think that once ProQuest has released customizable RSS feeds, other database vendors won’t be far behind. I’m waiting for the day I can get my Westclip and LexisNexis Eclipse results via RSS (hint, hint).
