AGRICOLA (AGRICultural OnLine Access), a database produced by the National Agricultural Library (NAL), consists of two subsets of records. The first contains citations for journal articles that include abstracts. The second consists of bibliographic records describing monographs, serials, audiovisual materials and online content from around the world. AGRICOLA includes but is not limited to resources available in the library. The database contains 5,200,000+ records and includes printed works from as far back as the 15th century.
AGRICOLA records describe publications and resources encompassing all aspects of agriculture and allied disciplines, including animal and veterinary sciences, entomology, plant sciences, forestry, aquaculture and fisheries, farming and farming systems, agricultural economics, extension and education, food and human nutrition, and earth and environmental sciences.
Both data sets are updated daily with newly cataloged and indexed materials. Each may be searched separately, or the two may be searched together. The NAL Catalog (AGRICOLA) may also be accessed on a fee basis through several commercial vendors, either online or on CD-ROM.
