The Memorial Library is located directly above Endecott Cafeteria and can be either be accessed from the first floor or in a strange piece of design from a set of stairs from the cafeteria. This causes a lot of student foot traffic through the library following lunch periods, much to the librarians' constant frustrations. Aside from this one piece of weirdness, the design of the library is in keeping with John Endecott Memorial's original design and like many of the original building rooms, it is known for its ability to get extremely hot and lack of air conditioning. Polished wooden bookshelves take up three-quarters of the room while the other quarter contains a collection of tables and chairs for students to sit and study. The library is open to all students throughout the week with the exception of Friday's where the use of the study space is reserved for the Seniors only, a practice that has been observed within the school since its founding.
