TITLE: How to be updated with current advances in mathematics 
QUESTION [17 upvotes]: Hello, 
I wanted to know that how researchers in mathematics keep updates in their field of interest. 
(original question by Rahul Gupta)

REPLY [5 votes]: The same as everyone else: arxiv, conferences, in my case "Number theory web", talking to friends and colleagues, etc. But I've come to realize that all of this keeps me updated about a very small portion of mathematics. To remedy this, once every couple of months I walk down to the math periodicals section of our library and spend an hour or so browsing the most recent issues of good journals: read abstracts, scan keywords, etc. I somehow find this very helpful; granted, by the time papers appear in print, they are for the most part outdated, but this still gives me a sense, though with some delay, as to what's going on in the mathematical world. In the same vein, I find the Notices of the American Mathematical Society very helpful.
