From librarian Aaron Schmidt (via facebook and Aaron's website):
The five library parks in Medellín, Columbia are amazing and not just because of their architecture.
Included in the network are five library parks, known as “hearts of knowledge.” Located throughout the city in some of Medellin’s most marginalized communities, the library parks have become cultural centers, providing broad, community access to information and educational resources. The network’s libraries offer a range of training programs, including how to use the computer and access information online, and English for the Internet.

The project was recently awarded the 2009 Access to Learning Award from the Bill & Melinda Gates Foundation.
