TITLE: Tools for Organizing Papers?
QUESTION [46 upvotes]: Much like a previous question on keeping research notes organized, my question is how people keep their pile of papers organized. I've got a stack of about 100 in my office, most of them classifying as "want to read", a couple "have read", and lots in between.

REPLY [3 votes]: There is a new tool called colwiz, which seems to have some advantages for mathematicians. In particular, it has MathSciNet support, unlike Mendeley. I wrote a summary of why I like it here.
