The new Edgartown Public Library will celebrate one year in its new location this Saturday, March 25, from 3 to 5 pm. Join Margot Datz at 4 pm in the Children’s Room, when she’ll introduce her marine-themed mural project. The 577-square-foot design will start on the east wall and wrap around to include parts of the north and south walls. Signed copies of her book “Nighttide on a Vineyard Farm” will be sold; proceeds go toward completion of the mural. All are welcome, and light refreshments will be served.
