The Pennsylvania School Librarians Association (PSLA) is an independent, incorporated professional organization, organized in 1972, for school library professionals who serve in the public and private schools of the Commonwealth of Pennsylvania and library educators from universities within the Commonwealth that offer bachelors and/or master degrees in school librarianship. The mission of the Pennsylvania School Librarians Association is to ensure excellence in school library programs.
PSLA provides school librarians with professional development opportunities and current information on school librarianship. Its members are advocates of high standards for librarianship and school library programs in the public, private, academic, and charter schools in Pennsylvania. PSLA cooperates with state and national organizations to improve all aspects of education, and supports the inherent right of the individual to have access to ideas and information. PSLA is an affiliate of the American Association of School Librarians (AASL), a division of the American Library Association (ALA).
