Abstract
AGRICOLA (Agricultural Online Access), the bibliographic data base of the National Agricultural Library, is a computerized information retrieval system that can be adapted for use in many library functions. Although the system is most commonly used for retrieval of bibliographic references by subject, it can also be helpful in preorder and precataloging searches, in interlibrary loan verification, and in collection analysis. Various bibliometric studies that can be done with the on-line versions of AGRICOLA are described as well.
