The MIT Libraries have launched the second puzzle in a series of puzzles that can be solved using Libraries’ resources. The puzzles will be released over the course of the Fall 2007 semester, appearing in the Tech, on kiosks in Lobby 7, and elsewhere around campus. MIT students can view the puzzle and submit their answers online at http://libraries.mit.edu/puzzle. Correct answers submitted by the deadline will be entered into a drawing for an Apple iPod Nano. The deadline for entries for the second puzzle is Tuesday, November 20, 2007. Congratulations to Mergen Nachin, winner of the first puzzle!
