reserve area

Alternatively, you can check the Reserve Collection at your college or university’s library. The Reserve Collection is a special area (usually near the Circulation desk) where professors leave designated materials for their students. Professors do this because they understand that books are costly and that not everyone can afford to purchase $200 textbooks.

Books held in the Reserve Collection usually have short borrowing periods of just an hour or two. The reason for the tight window is to give as many students as possible the chance to read a popular, required textbook. Books taken from the Reserve area are also usually supposed to be read only within the library; meaning you can’t take them out of the building. With some classes, there may be exceptions to this general rule, particularly if a professor approves a long-term borrowing option – with “long term” meaning anywhere from a day to perhaps as long as a week.

When a book is "on reserve" it means that the book cannot be removed from the "reserve room" or may be borrowed only for a short period of time. This process is usually done when the library has only a few copies of the book and it is required reading for a particular class.
