JournalTocs are worth a look, if you struggle to keep up with new articles and research findings. Take a look:- http://www.journaltocs.hw.ac.uk/
Zetoc is another good, reliable resource:- http://zetoc.mimas.ac.uk/.
Why not experiment to see which you prefer?
(You may also have heard of TicTocs - a similar service. This has now ceased, so you can lose that one from your favourites!)
