Getting started with the Cooper County plat book
If you're looking near Boonville, plat books are commercial atlases, that map ownership across the countryside, page by page across the county.
Getting to the right map

Around Windsor Place, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. For a home near Clifton City, copy the parcel ID before closing the panel; each records desk in the county uses it to find the file.
Getting answers from the right desk
Deeds, mortgages and recorded plats for land near Clifton City come from the Recorder of Deeds, usually searchable by name or document number. Building or septic questions for a lot near Otterville are for the local planning and health departments, depending on whether the land is inside town limits.
A word on accuracy
Listed acreage is an estimate; just a licensed surveyor establishes the real lines for a parcel near Big Muddy National Fish and Wildlife Refuge. For a home near Windsor Place, records update in batches, so a deed recorded last month can take weeks to appear.

Plat book vs. recorded plat
