Template:Cite enroute/doc

Usage
This template creates a cite book citation to the National Geospatial-Intelligence Agency Sailing Directions, including publication title, page, and year, plus a reference to the URL on the NGA web site that currently has the PDF of the publications (Pubs 120-200). Its use provides a standard citation for the Publications as well as making it easy to modify all citations globally if the NGA changes its web site organization, as happened with the US Coast Guard Light Lists in July, 2010.
