The United States Government Printing Office (GPO) was created in June 1860, and is an agency of the the U.S. federal government based in Washington D.C. The office prints documents produced by and for the federal government, including Congress, the Supreme Court, the Executive Office of the President and other executive departments, and independent agencies. The Coastal Zone Information Center (CZIC) collection provides access to nearly 5,000 coastal related documents that the U.S. Government Printing Office (GPO) received from the National Oceanic and Atmospheric Administration (NOAA) Central Library. The collection provides almost 30 years of data and information crucial to the understanding of U.S. coastal management and NOAA's mission to sustain healthy coasts. This is one of their documents.
