AGRICOLA (AGRICultural OnLine Access) serves as the catalog and index to the collections of the National Agricultural Library, as well as a primary public source for world-wide access to agricultural information. The database covers materials in all formats and periods, including printed works from as far back as the 15th century.
The 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.
Although the NAL Catalog (AGRICOLA) does not contain the text of the materials it cites, thousands of its records are linked to full-text documents online, with new links added daily. For information on how to obtain library materials not provided via such a link, see the Help text on Requesting Materials.
The NAL Catalog (AGRICOLA) is organized into two bibliographic data sets:
- The NAL Online Public Access Catalog contains citations to books, audiovisuals, serials, and other materials, most of which are in the Library's collection. (The Catalog does contain some records for items not held at NAL.)
- The Article Citation Database includes citations, many with abstracts, to journal articles, book chapters, reports, and reprints, selected primarily from the materials found in the NAL Catalog.
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, or its data file may be leased from the National Technical Information Service.
