Looking for a Tolland County plat book? A plat book shows owners and tract lines on township pages, and it's handy for land around Amston. Covered here for Tolland County: how the atlas is organized, where to look for printed copies, and how the county viewer fills the gaps.
Tracking down a Tolland County plat book
Around Ellington, a plat book is a privately published atlas, that map ownership across the countryside, page by page across the county.
Pulling up a parcel
Your first stop is the CT Parcel Viewer; it includes each assessed parcel from Hebron Center to Ellington. Without an address in hand, follow the nearest road on the aerial and click the parcel itself, and that holds around Amston too. On ground around Andover, copy the parcel ID while you have it open; every office in the county will want it.
Common uses
Buyers and seed dealers around Columbia rely on them to see ownership across many tracts at once.
A word on accuracy
The acreage figure is a tax-roll number; just a licensed surveyor can set the real boundary for a parcel near Ellington. In and around Ellington, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
How land is described here
Older tracts around Ellington commonly use metes-and-bounds descriptions, which trace the boundary call by call. Subdivision lots in Coventry are typically described by lot and block, making them easier to find. Write down the legal description for the tract near Coventry Lake for any title or survey request.
Finding a printed edition
Older editions near Hebron turn up in libraries and historical societies, which helps when tracing a farm's history.
The paper trail behind a parcel
The map is an index, not the title: deeds, plats and easements covering ground around Hebron Center are filed with the town clerk. Closer to Bolton, bring the book and page listed on the parcel record to skip a name search.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Coventry, but coverage can be spotty out of town. A saved image of the lot near Andover and its lines is a good backup.
A homemade atlas

Between editions
For acreage around Coventry Lake, the CT Parcel Viewer is updated more often than any atlas, across the county.

Two kinds of plat
A plat book is not a recorded plat: recorded plats near Ellington are filed with the town clerk, and the atlas is just a guide.
