YALSA. As you probably know, YALSA is the Young Adult Library Services Association. Through YALSA I have participated in exciting committees, met awesome authors, and traveled to cool places for conferences. More importantly it has helped me become an articulate and confident speaker, and given me ample opportunities to give back to the profession I love.
If you are interested in finding out how to get involved with YALSA, they have a website show you how to get involved, including a free webinar you can check out.
If you have any questions about YALSA involvement, and how to get started, please feel free to let me know! I've been on Popular Paperbacks, the Margaret A. Edwards Award committee, Great Graphic Novels, and the YALSA Board. Currently I'm serving on the Nomination Committee. Even if you aren't ready to go to conferences, there are many virtual ways to get involved!
