EI meaning in Community ?

The Essex Institute (1848–1992) in Salem, Massachusetts, was "a literary, historical and scientific society." It maintained a museum, library, historic houses; arranged educational programs; and issued numerous scholarly publications. In 1992 the institute merged with the Peabody Museum of Salem to form the Peabody Essex Museum.

On December 8, 2017, much to the dismay of Salem residents, Dan L. Monroe, PEM’s Rose-Marie and Eijk van Otterloo Director and CEO, issued a press release announcing that the 42,000 linear feet of historical documents will be permanently relocated to Rowley, MA and Plummer Hall and Daland House, the two historic buildings which had housed the Phillips Library, will be utilized as office and meeting space.
