What's inside a county plat book
Think of the St. Francois County plat book as a bound, printed version of ownership: township pages, owner names on each tract, and road maps for places like Leadwood. Don't confuse it with a subdivision plat on file for lots in Leadwood; that recorded plat is a legal document, while the atlas is a reference.

Using the St. Francois County map as a modern plat book

What a plat book page lists near Leadington

For a land purchase near Leadwood, rely on the county parcel record and a title search, not an atlas.
