How do you keep up with (non-periodical) conference proceedings?
I am not sure about EE, but for Computer Science, most of the venues you would usually want to track are listed in DBLP. DBLP itself does, as far as I know, not offer a subscription service, but (behold the beauty of open data) somebody else has built RSS feeds for DBLP.

This would allow you to use your favorite newsreader to keep up with conference publications the same way you are already tracking journals.
