DBLP is a nice database that indexes most all journals and conferences in theoretical computer science. To my knowledge, there is no good (single) mechanism for following the updates to these journals and conferences. In particular, DBLP does not have RSS feeds for the venues it tracks.
Using existing DBLP search features, I wrote some scripts to track updates to the venus in DBLP that I care about. The feeds (in Atom format) can be found below (click on the feed link). If you have any comments, or just find them useful, feel free to send me a note.
