How to remind a professor about sending papers to read?
Dear Professor X,
  
  during our meeting last week, you mentioned that you wanted to send me links to a couple of papers. Would you mind?
  
  Best, Y


I often find students agonizing over the exact wording of totally normal emails. The text above took me 10 seconds to write, and that's the amount of time you can expect the typical professor to spend on the typical email. You're not going to be held to a much higher standard either. Be polite, formal, and above all brief. Address the person at the top, sign off at the bottom. That's all that's being asked for.
