At the moment I am rather obsessed with Underground New York Public Library . The cool website, which describes itself as " a visual library featuring the Reading-Riders of the NYC subways", combines two things I really love: people watching and books.
My favourite thing about the site is that it lists the name and title of each book being read
(I find it so interesting to see who is reading what).
Trot over HERE to visit the site and see loads more photos.
