London Underground as Book Swap

The London Book Project is a scheme attempting to use the London Underground as a venue for a massive, and anonymous, book swapping ground. The project participants will distribute thousands of second-hand books throughout the Tubes and encourage others to do the same. The idea is simple, find a book, pick it up, read it, replace it or replace it with another book of your choice.

This is the kind of thing that gives new meaning to the term “underground library.”
