Collaborative Summer Library Program

The Collaborative Summer Library Program is a nonprofit, charitable organization that supports literacy, education and science through summer reading events in public libraries across the United States.

History

CSLP began in 1987 with ten Minnesota regional library systems that joined together to create a theme, artwork and program ideas for libraries to use for children's programming. It subsequently expanded to libraries throughout all fifty states and Washington D.C. to ensure all libraries can provide a high quality summer reading program. As of 2019, more than 4,800 libraries were participants.
