Abstract
The undergraduate library is a collection specifically set aside to serve the research needs of undergraduate students. Generally, it is in a building separate from the main research collection. Historically, it is a recent phenomenon, located primarily in the United States within the past 50 years. This entry will examine the reasons why this special collection is desired and developed, and continues to be useful in today's hyper-information-rich culture; and will look at the history, architecture, collections, and services of undergraduate libraries.
