Reserve readings are extra readings that professors make available in paper either through the library or their course pages (Moodle, the Wiki, etc.).
If you have Course reserve readings in the library, they will be listed on the Libraries Home page under COURSE RESERVES.
It will tell you which library the physical reserves are found.
They might be books, articles in folders, problem sets, films, lab keys, etc.
Reserves go out for short periods of time!
Be sure you know when they are due back: 2 hours, 4 hours, one day?
