I came across this cool blog called Underground New York Public Library that uses photographs to document what New York subway riders are reading. The blog is of obvious interest to me as a New Yorker, avid reader, and daily subway rider, but I recommend checking it out.
Besides providing me with a great place to read, my favorite part of riding the subway is scoping out what other people are reading. Now you can do the same while avoiding the crowds, smells, and other unpleasantries of the subway system (ok, those links make it seem worse than it is: don't be scared of NYC's public transportation system, I don't know what I and other millions of residents would do with out it!). Plus, the site has really nice photos.
