Folks,
The best place to look for the answer to this is the work _Shore and
Sea Boundaries_ by Aaron L. Shalowitz and Michael W. Reed
http://www.nauticalcharts.noaa.gov/hsd/shalowitz.html
You'll need to see Volume 2, Part 2, Chapter 1, p. 92-95.
http://www.nauticalcharts.noaa.gov/hsd/docs/CSE_library_shalowitz_v2p2ch1.pdf
When there's a string of dates in the lower left margin of a chart (in
this time period we're discussing), they each indicate a New Print
Date for the current edition. Some small corrections were incorporated
from the last print, but not enough to warrant calling it a new
Edition.
