Plat book vs. recorded plat

Common uses
Farmers, hunters and appraisers near Pecos Wilderness use plat books for a big-picture view of who owns what.
Where the recorded documents are
With a lot near Las Vegas, the map is an index, not the title: deeds, subdivision plats and easements for parcels in the county are kept by the County Clerk. Long-held tracts near Las Vegas can go back through several deeds, so a title company can sort it out if money is changing hands.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near North San Ysidro, but coverage can be spotty out of town. A screenshot of the parcel near Ribera with its ID helps when you meet an owner or agent.
