The most important medium of communication in the sciences is the peer reviewed journal. Many scientists keep up with the literature in their specific field by reading certain journals as they are issued or by using some type of a current awareness tool. In order to do a comprehensive search for journal articles on a particular topic, however, it becomes necessary to use a periodical index. Fortunately, advances in computer technology have made it possible to store volumes of information on CD-ROM or magnetic media. Searching for the information has become faster and more sophisticated searches can be conducted.
Periodical indexes are usually specialized and cover a particular subject area.
They may or may not cover other types of publications such as theses and dissertations, government reports, conference proceedings, patents, etc. Copley Library owns the print version of this index. Covers all academic subjects. Allows for simple keyword in title searches, author searches, and journal browsing. Available only to current USD students, faculty, and staff.
