AGRICOLA is a bibliographic database of citations to the agricultural literature created by the National Agricultural Library (NAL) and its cooperators. Production of these records in electronic form began in 1970, but the database covers materials in all formats, including printed works from 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. Many AGRICOLA records are linked to full-text documents online, with new links added daily but check IUCAT or Find Information for additional sources available to IU Bloomington users. The AGRICOLA database is organized into two bibliographic data sets. Each data set may be searched separately, or they may both be searched together. AGRICOLA also contains some bibliographic records for items cataloged by other libraries but not held in NAL's collection.
