From the CBC:
The library in Cardigan [P.E.I], operated by John A. MacDonald, sits in a building that measures 3.5 x 3.5 metres, and holds about 1,800 books. A lifetime membership costs $5, and it runs on an honour system. If you sign out a book, you’re expected to bring it back.

MacDonald has contacted Guinness World Records, but officials said there isn’t a category for the world’s smallest library. MacDonald is hoping the organization will consider creating one, and that his library will win the title.
