Getting started with the Oldham County plat book
Town lots near US Route 385 are usually too small to label, which is where the parcel viewer helps.
Opening the official parcel viewer
Begin with the appraisal district interactive map; it maps each assessed parcel from US Route 385 to Vega. If you only know roughly where the land is, zoom in from US Route 385 and click the parcel itself. With a lot near US Route 385, copy the parcel ID before closing the panel; every clerk in the county will want it.
A word on accuracy
Tax maps are drawn for assessment, not surveyed, so a fence near Interstate 40 often sits a few yards off the line on screen. Records update in batches, so a fresh transfer around US Route 385 can take weeks to appear.
Which office to call
For assessment questions about property around Interstate 40 are handled by the appraisal district, which maintains the tax roll. Questions about what you can build around US Route 385 go to planning, building or health offices, and the answer depends on jurisdiction.
Printing your own
Screenshot each section of the viewer around US Route 385 to build your own up-to-date atlas.
Finding a printed edition
Older editions near US Route 385 turn up in libraries and historical societies, useful for family or title research.
A quick look at the area
Vega is the county seat, which is where the courthouse records live. You'll also find Adrian, Boys Ranch, Wildorado, and Canadian River. Roughly 1,783 people call Oldham County home (Census Bureau estimate, 2023) spread over about 1,501 square miles. Oldham County dates to 1881, which matters when you trace an old farm's title. Features like Canadian River are easy to spot when you zoom out.
Who uses plat books

Between editions
For current names, use the appraisal district interactive map, across the county, for land near Wildorado included.
Sections, lots and bearings
Older tracts around Interstate 40 commonly use metes-and-bounds descriptions, listing bearings, distances and landmarks. Town lots near US Route 385 refer to a recorded plat, which is simpler to follow. Keep the legal description for land near Interstate 40 when you talk to a surveyor.
Deeds, plats and who keeps them
The map is an index, not the title: recorded deeds, subdivision plats and easements for land near Interstate 40 are kept by the County Clerk. Older tracts near US Route 385 can trace back through many deeds, and a title company can sort it out on a real sale.
Two kinds of plat
For property near US Route 385, don't confuse the atlas with a recorded subdivision plat: the recorded plat at the County Clerk is a legal document, and the atlas is just a guide.
Using it on a phone
Most viewers work in a phone browser, which helps when you're standing on land near US Route 385, but coverage can be spotty out of town. A screenshot of the parcel near Interstate 40 with its ID helps when you meet an owner or agent.
When a parcel crosses a boundary
Oldham County touches Quay County, NM, Deaf Smith County, Hartley County, Moore County, and Potter County; every one of them runs a separate parcel map. A tract near the line by Interstate 40 may be split across two assessors' files, so check the adjacent map too.
