After School Library Use

As a student who finds himself staying after school frequently, I am frustrated at the fact that I am unable to utilize our school library for academic work. To my understanding the school library is a shared space and should not be dominated by a single group. However, whenever I've tried to work on homework whithin the library my concentration is greatly hindered by chatting, and often yelling, middle school students attending an after school program, "Spring-Board". While I don't disagree with what they're doing (They're children having fun and learning, who could hate that?) I do disagree with the fact that it is occurring in the library, an understood "quiet-zone". I popose for "Spring-Board to be held elsewhere (the cafeteria?) so that other students, middle school and high school alike, can fully utilize the library to complete academic work.
