In the years from 1907 to 1910,Frank W. Stickneprepared a map of the Town of Concord, showing new Town boundaries as well as Parcel boundaries and Parcel Owner names. Town Archivist Nathanial Smith has procured very-high-resolution scans of these maps for public viewing.
You may view these images in this web app, which allows you to slide an overlay of the current parcel layer on and off, to see what's changed in Concord since the turn of the previous century.
