When you assign a project that requires your students to use Library resources, it is helpful to us if we know about the assignment ahead of time. This ensures that the first student who visits us does not check out every book we have on the subject. With notice, we have the opportunity to set a collection of appropriate materials aside on a temporary reserve basis. By holding back some of our available materials for use within the building (as opposed to being checked out), we can be sure that material is available to all of your students.
