SLMSSENY is a professional organization comprised of over 250 school library media specialists in southeastern New York. We are one of eight regional affiliates, which make up the School Library Media Section of the New York Library Association.

Our mission is to advocate for and promote the interests of the school library media specialists in southeastern New York so that they can enable students to become independent learners and avid readers. We facilitate this mission by assisting and encouraging our members, actively lobbying for increased support of school library media programs and school library systems, presenting a dynamic Spring Conference, and providing opportunities for professional development. In addition, we give the annual Rip Van Winkle Award for outstanding contributions in the field of children's literature by an author/illustrator residing in the seven county SLMSSENY region and keep intellectual freedom alive in every school library media center.
