The Cooperative Children’s Book Center (CCBC) has been serving Wisconsin public and school librarians since it opened its doors in 1963. Across the years, what those services look like have changed, but the library’s commitment to maintaining a hands-on book examination center and providing in-depth information about literature for children and teens and related issue has been constant.  CCBC librarians Merri Lindgren and Megan Schliesman provided this overview of current CCBC services to Wisconsin librarians, including the library’s annual best-of-the-year list and intellectual freedom information services, and an in-depth look at resources on the CCBC’s revamped web site, for the Wisconsin Association of Public Librarians (WAPL) Annual Conference, May 5, 2021.
