U.S. Department of Agriculture’s Alternative Farming Systems Information Center (AFSIC) specializes in identifying resources about sustainable food systems and practices in support of USDA’s effort to ensure a sustainable future for agriculture and farmers worldwide. AFSIC has a directory that contains links to online searchable databases that pertain, in some degree, to sustainable/alternative agriculture. The directory contains book and article citations and abstracts, research project descriptions, full-text documents and spreadsheets, organizational contact information, plant and animal production information, and other kinds of data.
