Photographs of Concord, Mass. (houses and buildings, street and area views, cemeteries, landscape views, North Bridge views) taken by E.F. Worcester between about 1900 and about 1915; also, five (earlier?) West Concord photographs not taken by Worcester but, long stored with Worcester negatives. Many of the images included among the negatives were used in Worcester's Concord and Lexington ... and in Swayne's The Story of Concord.
