Staffed by a full-time librarian, the ACDS library is open at all times that school is in session. Students in kindergarten through fifth grade visit the library once or twice per week to hear stories, pursue research, and develop information and media literacy skills. Students in all grades working on special projects may use the library at any time; they may be assisted by the librarian, their classroom teacher, or may work independently depending on the circumstances. The library is open during middle school recess every day and the librarian works with middle school teachers to arrange library visits for recreational reading and curriculum-related work.

The collection consists of nearly 12,000 titles including books, videos and dvds, magazines, audio tapes and CDs, iPods and Playaways. Anyone in the school community, including students, teachers, staff, and parents, may borrow items.
