Reserves are held at the Sherman Fairchild Library (SFL). There are two types: open and closed. Open means they are out on the shelves, organized by course, and you can go get them yourself. Closed means they are held behind the ciruclation counter, and you have to ask for them. The borrowing time for both is 3 hours. Returning reserves on time is considered a part of the honor code. The catalog will tell you the location of a reserve and its type.
At the moment, we are working on migrating to an new library catalog. To access course reserves, go here and click "course reserves" under the search box.
