Although cited reference studies are common in the library and information science literature, they are rarely performed in non-academic institutions or in the atmospheric and oceanic sciences. In this paper, we analyze over 400,000 cited references made by authors affiliated with the National Oceanic and Atmospheric Administration between 2009 and 2013. Our results suggest that these methods can be applied to research libraries in a variety of institutions, that the results of analyses performed at one institution may not be applicable to other institutions, and that cited reference analyses should be periodically updated to reflect changes in authors' referencing behavior.
