The purpose of the library is to be an intellectual force in the Westover School community. This purpose is accomplished by assisting students as they formally and informally pursue their education. Materials and instruction support the curriculum and academic philosophy of the school, and supplement and complement courses offered by faculty. The Library, dedicated in 1984, affords a spacious, comfortable, and visually appealing place for students to work, to do research, or simply to curl up in a sunlit corner to read. The library affords a variety of spaces, both for individual study and for communal work.

The librarians are available for one-on-one help to students and faculty. If students need more help than is available in a short time, they are encouraged to make an appointment with a librarian for further assistance. By fostering a quiet, studious atmosphere, the library affords an area for completion of homework and research assignments. Class research projects are supported in the library through reserve areas for books and magazines.

Library and research skills are covered in Elements of Research, a mini-course taught by the librarians in conjunction with a research project undertaken by students in Introductory Biology. Topics include the use of two research websites, the InfoCentre Online Catalog and the Connecticut Digital Library. Students also learn to evaluate websites, take notes, properly cite  textual source, and write a bibliography.
