A couple years ago when I started thinking about doing an REU (Research Experience for Undergraduates) or internship in math, I began a database of all the information I thought might be useful as I encountered it. While participating in the University of Nebraska-Lincoln REU this summer and talking with the other students, it occurred to me that the information I collected during my pre-application phase -- due dates, support information, application checklists for many Math REUs and internships -- might be useful to others. So I put it up on Google Docs. Here's the link: http://tinyurl.com/UMathResources" [Broken] One of the most frustrating things I kept encountering when I was looking for REUs and internships was the frequent broken links, which are rather inevitable since many times the specific url for a page changes slightly from year to year. If you notice a broken link in one of these spreadsheets, just click the linky to edit and you can update the info and do everybody a favor. I'm thinking of working on something similar for grad math programs, but that seems kind of daunting. Anyone interested in maybe helping, though? Edited to add: Mods--I'm new to PhysicsForums and I tried to select the most appropriate forum for this post. I'm open to correction, though, if it more properly belongs somewhere else.
