The printed Barnstable County plat book and the online parcel map answer the same question, who owns the land near Dennis, in different ways. Below is how to track one down for Barnstable County, MA, and what the online map does better.
How to use the Barnstable County plat book

Current and older editions

Atlas details and limits
