I receive monthly Table of Contents [ToC] alert emails from specific journals in which I'm interested, mainly chemistry and physics. This typically involves simply creating an account at the publishers website and choosing which of their journals you'd like to receive ToC alerts for, e.g. the American Chemical Society (acs.org), and then sign up for e.g. Journal of Chemical Theory and Computation alerts.

Also, for computational chemistry, at least, there's the Computational Chemistry Highlights blog [ http://www.compchemhighlights.org/ ], which selects (what they think are) interesting papers published within the past two years or so.

Finally, I follow scientiests' blogs and social media, who will typically share excellent papers that they find. Email lists like the Computational Chemistry List [ ccl.net ] will usually discuss papers as they relate to the conversations at hand.

Unfortunately, many of the excellent chemistry journals are behind pay walls.

This is how I harvest info for chemistry. I think it's highly probably that this same method could be used for all scholarly disciplines.

Best of luck.
