A word on accuracy
Tax maps are drawn for assessment, not surveyed, so the edge of a yard near Butte des Morts often sits some distance off the line on screen. Owner names and values update on a schedule, so a fresh transfer around Appleton can take weeks to appear.
Sections, lots and bearings

Recorded documents worth pulling
If you're looking near Oshkosh, the map is an index, not the title: deeds, subdivision plats and easements for parcels in the county are filed with the Register of Deeds. For acreage around Oshkosh, have ready the instrument number listed on the parcel record so staff can find the deed fast.
Using the parcel viewer instead
