Plat books vs. recorded plats in Mineral County
Think of the Mineral County plat book as a bound, printed version of ownership: township pages, owner names on each tract, and road maps for places like Superior. Don't confuse it with a subdivision plat on file for lots in Superior; that recorded plat is a legal document, while the atlas is a reference.
Search Mineral County parcels by owner, address or ID
The county's own public map is the Mineral County ArcGIS parcel map, built on an Esri ArcGIS web map, and it opens without an account for parcels in Superior and the rest of the county.

Finding a printed Mineral County plat book
Whether a current Mineral County edition exists varies, so ask locally in Alberton before ordering; county offices frequently know if one is in print. Collectors and genealogists prize old Mineral County atlases since they show farm names and owners near Riverbend long before online maps.
What a plat book page lists near Superior
A typical atlas page for a township near Superior lists sections, roads and streams, with each ownership block labeled. Small parcels and town lots in Superior are frequently too small to label on an atlas page, which is another reason the online map is better for them. If you use a plat book for hunting permission near Superior, recheck the titleholder on the county map first.
