Looking for an Otsego County plat book? It's a printed atlas of landownership, usually by township, useful for farms near Edmeston. This Otsego County guide covers: how the atlas is organized, where to look for printed copies, and how the county viewer fills the gaps.
The Otsego County plat book: start here
Around East Worcester, plat books are commercial atlases, with owner names on each tract, page by page across the county.
Pulling up a parcel
Begin with the NYS Tax Parcels Public layer in ArcGIS Map Viewer; it includes each tax parcel around Burlington Flats and Fly Creek. If you only know roughly where the land is, follow the nearest road on the aerial and select the outline, whether the land is near Cherry Valley or elsewhere in the county. For property near East Worcester, write down the parcel ID while you have it open; every clerk in the county uses it to find the file.
Backing up the map with records
For anything that matters, request the recorded deed from the County Clerk; the viewer just points to it, which applies near Hartwick as much as anywhere. Long-held tracts near Fly Creek may go back through several deeds, so a title company can sort it out before a purchase.
Sections, lots and bearings
Older tracts around East Worcester commonly use metes-and-bounds descriptions, a series of courses and distances from a starting point. Town lots near Decatur usually use lot and block from a recorded plat instead, making them easier to find. Write down the legal description for the tract near Edmeston for any title or survey request.
Why people still buy them
Buyers and seed dealers around Decatur rely on them to see ownership across many tracts at once.
Taking the map into the field
Most viewers work in a phone browser, handy when you're parked on a road near Decatur, so load it before you lose signal. A printout of the tract near Hartwick keeps working without signal.

Otsego County in a few facts
Cooperstown serves as the county seat, home to the main records offices. You'll also find Oneonta, Burlington, Butternuts, and Cherry Valley, where town lots give way to larger tracts. Roughly 60,126 people live in Otsego County (Census estimate, 2023) spread over some 1,002 square miles. The county dates to 1791, and some chains of title near Hartwick are long.
Limits of the parcel data
Out toward Fly Creek, listed acreage is a tax-roll number; only a licensed surveyor can set the real boundary on the ground. Near Burlington, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Offices that can help
If the acreage or value on a parcel near Cherry Valley looks off belong with the county Real Property Tax Services office, since that office keeps the assessment data. Building or septic questions for a lot near Decatur go to planning, building or health offices, depending on whether the land is inside town limits.
Editions and availability
Older editions near Fly Creek turn up in libraries and historical societies, useful for family or title research.
Between editions
In and around Burlington Flats, the NYS Tax Parcels Public layer in ArcGIS Map Viewer is updated more often than any atlas, across the county.
Not the same thing
On ground around Burlington Flats, a plat book is not a recorded plat: the recorded plat at the County Clerk is a legal document, and the atlas is just a guide.
When a parcel crosses a boundary
Otsego County borders Chenango County, Delaware County, Herkimer County, Madison County, and Montgomery County; every one of them runs a separate parcel map. Acreage along the edge near Hartwick can show up in two county records, so check the neighboring map too. For a tract near Garrattsville, our state page lists each bordering county map for New York.
