While most librarians turn to the American Library Association and assorted divisions for their professional association needs, there are several other options that can provide resources for librarians depending on your particular interests.
The National AfterSchool Association is for “professionals who work with children and youth in diverse school and community-based settings to provide a wide variety of extended learning opportunities and care during out-of-school hours.” This is a perfect fit for public librarians who provide programming for youth of all ages, and even school librarians who provide programs after school. Whether or not you join the association, they offer lots of free resources to help plan and facilitate programs, including the Tip of the Week, a Resources section, and an email newsletter.
The Assembly on Literature for Adolescents (ALAN) is a division of the National Council of Teachers of English dedicated to promoting young adult literature. Resources to be aware of include the Amelia Elizabeth Walden Award for a YA book that “exemplifies literary excellence, widespread appeal, and a positive approach to life” and the annual ALAN Workshop, which coincides with the NCTE conference. ALAN also has helpful resources to deal with book challenges and several publications, including the ALAN Review (some content is free to non-members).
The International Society for Technology in Education (ISTE) serves “educators and education leaders committed to empowering connected learners in a connected world.” If you’re using technology with teens in your library, this organization may be a fit for you. They have a robust online community and professional learning networks on various topics to join. The ISTE Connects blog and the free resources section offer lots of tips and resources and are open to non-members.
