Tracking down a Penobscot County plat book
For acreage around Baxter State Park, plat books are commercial atlases, with owner names on each tract, page by page across the county.
The viewer Penobscot County publishes
Parcels around Drew Plantation are published on the Maine GeoLibrary Parcel Viewer, which opens without registering. For a parcel near Webster Plantation, enter a street address, an owner's name or a parcel number, and the matching parcel lights up. For property near Old Town, copy the parcel ID before closing the panel; each clerk in the county will want it.
What the map can't tell you
The acreage figure is an assessed number; just a licensed surveyor sets the real corners on land around Sunkhaze Meadows National Wildlife Refuge. Owner names and values update on a schedule, so a recent sale near Sunkhaze Meadows National Wildlife Refuge may not show yet.
Getting your bearings
Bangor serves as the county seat, where most land records are kept. You'll also find Brewer, Old Town, Alton, and Bradford, where town lots give way to larger tracts. About 155,312 people call Penobscot County home (Census estimate, 2023) spread over roughly 3,397 square miles. Penobscot County was formed in 1816, so old deeds can run back a long way. Features like Baxter State Park help you orient on the aerial.
When a parcel crosses a boundary
Penobscot County meets Aroostook County, Hancock County, Piscataquis County, Somerset County, and Waldo County, all with their own assessor records. Ground near Brewer that runs to the line may be split in two county records, so look at the neighboring map too. Around Bradford, our state page links every bordering county map for Maine.
Offices that can help
Questions about value or the owner field for land near Bangor belong with the town assessor, which maintains the tax roll. Zoning, permits and septic questions near Drew Plantation go to planning, building or health offices, depending on whether the land is inside town limits.

Using the parcel viewer instead

On site with the map

Backing up the map with records

Atlas or legal document
