    Much of the early Coast Survey telegraphic longitude work is described
    in their annual reports, online here:
    
    https://library.noaa.gov/Collections/Digital-Collections/USCGS-Annual-Reports
    
    The reports are indexed in the bibliography, available on the same page.
    A good deal of navigational content is there as well, since this
    organization was responsible for hydrographic surveys.
    
    In the 20th century, stuff that was formerly in the appendices of the
    annual reports was instead printed as "special publications". These are
    available on a different page at the same site. Some deal with geodetic
    astronomy.
