The Library maintains a collection of instructor reserve materials. These consist of textbooks, videos, and supplemental course materials that instructors have put in the Library for student use. To find what materials are available for Oceanography, search Course Reserves in the Online Catalog. It is best to search by "Course Number" (ex. OCEA 101) in that an instructor other than yours may have placed an item on reserve. Materials can be requested at the Periodicals counter and generally must be used in the Library on a two-hour loan period. Photocopy machines are available for 10¢ a copy.
