Covers publications and resources encompassing all aspects of agriculture and allied disciplines including: animal and veterinary sciences, entomology, plant sciences, forestry, aquaculture, economics, education, food and human nutrition, and earth and environmental sciences. AGRICOLA is produced by the National Agricultural Library. This database includes selected materials dating back to the 17th century but full coverage starts in 1970.
PubAg is a portal to USDA-authored and other highly relevant agricultural research. Launched in January 2015, it delivers over 40,000 full-text journal articles by USDA staff and includes nearly 450,000 citations. It will replace Agricola as more bibliographic references are added.
