LibrariUS is a co-production of American Public Media's Public Insight Network (PIN), the American Library Association (ALA) and its division, the Public Library Assocation (PLA). The purpose of this project is to explore the information and other needs of communities through the lens of local libraries.

PIN is a nonprofit network of more than 100,000 people around the country who share their insights, knowledge and experiences with trusted journalists in hopes of making news coverage more relevant, transparent and trustworthy. It was founded eight years ago by American Public Media, the second largest producer and distributor of public radio programming and the largest owner of public radio stations in the nation.

ALA is the oldest and largest library association in the world, with more than 61,000 members. The nonprofit organization promotes libraries and information services, and librarianship internationally, to ensure that everyone has access to information.

PLA is a division of the ALA. PLA's core purpose is to strengthen public libraries and their contribution to the communities they serve. Its mission is to enhance the development and effectiveness of public library staff and public library services.
