Hi Melanie!
First of all, Welcome to IFRT! We typically start planning for the next terms (they begin on July 1/during Annual conference for ALA) in the Spring. In the case of IFRT, the incoming chair (our chair-elect right now is Wanda) will start to make committee appointments in the next couple of months. Submitting the volunteer form now for July puts you in a good place!
IFRT also has an Active Member List: Member List | Intellectual Freedom Round Table that you can fill out to let IFRT leadership know that you are interested in opportunities to actively engage in IFRT.
Happy to have you on board promoting the Freedom to Read!
