19th century Long Island charts

19th c. Long Island nautical charts

These large hand-colored engraved charts of Long Island Sound and the Connecticut coastline were acquired for the library in 2012, and were notable features of the 15th anniversary exhibition.  Published in 1855 as aids to navigation, they include several tiny engravings of prominent coastal landmarks to assist sea captains in confirming their offshore position. The three charts depict the full length of Long Island Sound, from New York's East River estuary to Block Island. A magnifying glass allowed visitors to examine the many pictorial details.
