Michigan participates in the Collaborative Summer Library Program. The Collaborative Summer Library Program (CSLP) is a grassroots consortium of states working together to provide high-quality summer reading program materials for children at the lowest cost possible for their public libraries. By combining resources and working with a commercial vendor to produce materials designed exclusively for CSLP members, public libraries in participating states or systems can purchase posters, reading logs, bookmarks, certificates and a variety of reading incentives at significant savings. The participating systems and states develop a unified and high-quality promotional and programming product. Participants have access to the same artwork, incentives and publicity, in addition to an extensive manual of programming and promotional ideas.
