Barnes & Noble will host a book signing event on Oct. 10 for local author Peggi Medeiros. The signing is scheduled for 2 p.m.

Mederios is a historian and author of a new book, “New Bedford Mansions: Historic Tales of County Street.”

Her book explores the historical significance of the mansions of New Bedford and delves into the people who lived there. Much of her new book stems from her work in the late ‘70s with New Bedford’s Office of Historic Preservation.

Barnes & Noble is located at 392 State Road.
