This is a pretty outdated (2009) news article but it is such a brilliant idea that it deserves to go under my list of Unconventional Libraries:
BBC news article :Phone box has new life as library
“The bright red phone booth was purchased by the Westbury-sub-Mendip Parish council from BT for a mere £1, and residents soon began to install shelves and stock them with books that they’ve read, with the opportunity of swapping them out for ones they’ve not. A major success, the library is filled with over 100 choices ranging from cookbooks to classics, from blockbuster DVDs to old school CDs.
While traditional in its aesthetic, the library has a very convenient modern feature: it’s open 365 days a year, 24 hours a day, and even lit at night for those who want a book to curl up with a book before dozing off. In order to keep the selection fresh, there is even a regular check to determine which titles are moving — those failing to capture the eyes of the locals are shipped off to a charity shop.”
A library for the community by the community!
