Want a copy of the Calhoun County plat book? These atlases map who owns rural land, page by page, popular with hunters, farmers and buyers near Centerville. Covered here for the county: how the atlas is organized, where to look for printed copies, and how the county viewer fills the gaps, at least around Batchtown.
Getting started with the Calhoun County plat book
Closer to Belleview, plat books are commercial atlases, with owner names on each tract, often organized by township.
The viewer Calhoun County publishes
Begin with the Calhoun County parcel viewer; it includes every assessed parcel around Deer Plain and Illinois River. Without an address in hand, follow the nearest road on the aerial and click the parcel itself, whether the land is near Batchtown or elsewhere in the county. For a parcel near Centerville, write down the parcel ID before closing the panel; every records desk in the county uses it to find the file.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Kampsville, though signal can drop in rural spots. A printout of the tract near Belleview keeps working without signal.
Who handles what
Recorded documents for a parcel near Brussels are with the county Recorder of Deeds (in many counties the County Clerk and Recorder), sometimes only in person. Zoning, permits and septic questions near Beechville need the planning or permitting office, town or county, depending on location.
Who uses plat books
Farmers, hunters and appraisers near Beechville use plat books to see ownership across many tracts at once.

Before you lean on the lines
Listed acreage is an assessed number; just a licensed surveyor can set the real corners for a parcel near Mississippi River. Around Illinois River, records update in batches, so a deed recorded last month might lag behind.
Deeds, plats and who keeps them
For anything that matters, request the recorded deed through the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel line is a drawing of it, which applies near Brussels as much as anywhere. If you're looking near Kampsville, older tracts in the county may go back through many deeds, and a title company earns its fee before a purchase.
Editions and availability
Older editions near Great River Road turn up in libraries and historical societies, which helps when tracing a farm's history.
Getting your bearings
Hardin serves as the county seat, home to the main records offices. Smaller places on the map include Batchtown, Brussels, Hamburg, and Kampsville, each with its own cluster of lots. About 4,317 people call Calhoun County home (Census Bureau estimate, 2023) across some 254 square miles. The county was organized in 1825, and some chains of title near Mississippi River are long. Places such as Mississippi River, Illinois River, and Two Rivers National Wildlife Refuge make handy reference points on the map near Great River Road.
Sections, lots and bearings
Illinois follows the Public Land Survey System, so deeds around Belleview reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Brussels can be irregular. Keep the legal description for land near Belleview for any title or survey request.

Plat book vs. recorded plat
