Old copies of the Kennebec County plat book turn up at auctions and in kitchen drawers around Belgrade, and new ones are harder to track down. Below is how to track one down for Kennebec County, ME, and what the online map does better.
What a Kennebec County plat book is
A plat book, sometimes called a land atlas, lists each township in Kennebec County as a page, with ownership blocks labeled by owner name and rough acreage. Don't confuse it with a subdivision plat on file for lots in Benton; that recorded plat is a legal document, while the atlas is a reference.
Finding the tract on the Kennebec County map
Kennebec County parcels are viewed through a statewide map, the Maine GeoLibrary Parcel Viewer; zoom toward Hallowell to reach them. Use the search box for an address in Hallowell or a parcel number, or simply zoom in and click a parcel near Belgrade. If the official address for the Kennebec County, ME map ever changes, our directory page carries the current link for Hallowell and the rest of the county.
Where Kennebec County plat books turn up
Whether a current Kennebec County edition exists varies, so ask locally in Waterville before ordering; county offices commonly know if one is in print. Older editions are useful for family history around Benton, showing who held a farm decades ago.
Reading a Kennebec County atlas page
Many atlases add rural residence listings and road maps, handy on back roads near Winthrop. Small parcels and town lots in Benton are commonly too small to label on an atlas page, which is another reason the online map is better for them. Genealogists in Maine commonly pair an old Kennebec County atlas with deed records to follow a farm through the generations.

The lay of the land around Augusta
