Description:
AGRICOLA (AGRICultural OnLine Access) 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. Although the AGRICOLA database does not contain the full-text materials, thousands of AGRICOLA records are linked to full-text documents online, with new links added daily.
ArchiveGrid provides a guide to locating historical collections around the world, with nearly a million collection descriptions. ArchiveGrid does not provide full-text, but does act as a guide for knowing where specific documents and collections are housed.
