PubAg is a new search engine and portal for published USDA research. It supports free full-text access of more than 40,000 scientific journal articles by USDA researchers, mostly from 1997 to 2014. It, as of January 2015, provides access for searches of 340,000 peer-reviewed agriculturally related scientific literature, mostly from 2002 to 2012, each entry offering a citation, abstract and a link to the article if available from the publisher. Later in 2015, it will include the remainder of NAL's significant bibliographic records. New articles by USDA researchers will be added almost daily, and older articles may be added if possible.
