Our Take

AGRICOLA is the agricultural counterpart to a free government index like ERIC or PubMed — the National Agricultural Library’s catalog of journal articles, reports, and the grey literature that agricultural research generates in volume. For food science, agronomy, and related fields it is a solid, free starting point, especially for USDA and North American material. The limits are that it is U.S.-leaning and less comprehensive internationally than the big subscription indexes, and inclusion is not a quality filter. Use it as your free agricultural index; pair with CAB Abstracts or Scopus for global comprehensiveness.

Power Tips

  • Use it to surface USDA and North American grey literature — reports and bulletins the commercial indexes miss.
  • For a comprehensive international review, pair it with CAB Abstracts or FSTA.
  • Filter carefully; inclusion here is not a peer-review guarantee.
