Children and adults can now check out books for free from tiny libraries in over 50,000 neighborhoods in 70 different countries. Some libraries are built with sustainable materials, some consider height differences between kids and grownups, while others are just plain fun. The organization behind these free exchanges, Little Free Library, recently held a Little Free Library Design Competition that drew an astonishing 300 designs from 40 countries. Check out the winners after the jump.

Friendly Owlie library has eyes that glow at night

Owls are commonly associated with wisdom. So an owl outline offered the perfect shape for Bartosz Bochynski’s tiny library, called Owlie. Bochynski, who is of design studio FUTUMATA in London, England, said Owlie could be constructed with affordable, sustainable materials and lit with LED lights. The friendly little library can hold around 40 tomes, some of which can be seen through the owl’s eyes which light up at night. Owlie was the judge’s choice in the competition.

Sleek little library with removable parts allows for easy customization

Seth Thompson of San Francisco, California designed a little library designed for effortless rearranging. With a removable plexiglass door and shelves, the little library could accommodate a hanging flower planter, according to Thompson, and stewards can write on the door with dry-erase markers. Snøhetta San Francisco, one of the competition’s judges, described Thompson’s library as iconic, earning him the judge’s choice runner-up award.

Little library in Ohio transforms into community center

The 4th Street Farms Little Free Library is more than just a design concept; it’s already a fixture of its Columbus, Ohio neighborhood and has morphed into a mini community center offering a Little Food Pantry alongside books. Mural elements from local artists adorn the library, and varying shelf heights allow patrons of all ages to explore offerings. Motion sensor lighting brightens the space day or night.
