When a listing near South Roxana mentions a lot number, look up the Edwardsville plat map it refers to. Covered here for the city: where plats are filed, plat versus tax map, and the details that matter to buyers, especially near Alton.
Tracking down the Edwardsville plat map
For a subdivision near Maryville, look for the plat book reference on the parcel record; bring that to the recorder's office or its online index.
Getting to the right map
Begin with the Madison County parcel viewer; it maps each tax parcel in the county, Glen Carbon included. When a rural tract has no street number, follow Interstate 255 on the aerial until the lines appear, then click inside the one you want. If you're looking near Hartford, write down the parcel ID before closing the panel; every records desk in the county will want it.
On site with the map
Most viewers work in a phone browser, useful out on a road near South Roxana, but coverage can be spotty out of town. A saved image of the lot near Hartford and its lines helps when you meet an owner or agent.
Neighboring parcel maps
Madison County touches Bond County, Clinton County, Jersey County, Macoupin County, and Montgomery County, all with their own assessor records. Acreage along the edge near Roxana may be split across two assessors' files, so check the adjacent map too. For acreage around South Roxana, the Platbookmapper state page lists each bordering county map for Illinois.
When a plat changes
An amended plat may change lots around Roxana, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
Metes and bounds instead
Rural land near Glen Carbon that was never subdivided is often described by metes and bounds or survey description; look for a recorded survey for land there.
Who handles what
Recorded documents for a parcel near Roxana sit in the index kept by the county Recorder of Deeds (in many counties the County Clerk and Recorder), usually searchable by name or document number. Zoning, permits and septic questions near Roxana are for the local planning and health departments, depending on whether the land is inside town limits.
City limits and county records
Edwardsville is part of Madison County, Illinois, which means parcel data comes from the county. Edwardsville is also the county seat, handy when you need recorded documents. Local government in Edwardsville handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Acreage past the town limits near Hartford generally follows county rules rather than the town's.
Two different maps
The Madison County parcel viewer draws parcels for taxes, whereas the plat carries surveyed dimensions.

Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Pontoon Beach can be irregular. Write down the legal description for the tract near Maryville before you request a deed or survey.

What the map can't tell you
Acreage on the record is an assessed number; only a licensed surveyor establishes the real corners for a parcel near Pontoon Beach. Owner names and values update on a schedule, so a fresh transfer around Glen Carbon can take weeks to appear.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
