The printed Hancock County plat book and the online parcel map answer the same question, who owns the land near Bar Harbor, in different ways. Below is how to track one down for Hancock County, ME, and what the online map does better.
What's inside a county plat book
Think of the Hancock County plat book as a bound, printed version of ownership: township pages, owner names on each tract, and road maps for places like Aurora. Don't confuse it with a subdivision plat on file for lots in Aurora; that recorded plat is a legal document, while the atlas is a reference.
Step one: the free Hancock County viewer
For Hancock County, the free public parcel layer is state-run: open the Maine GeoLibrary Parcel Viewer and pan to Blue Hill. Use the search box for an address in Brooklin or a parcel number, or simply zoom in and click a tract around Blue Hill. If the official address for the Hancock County, ME map ever changes, our directory page carries the current link for Brooklin and the rest of the county.
Finding a printed Hancock County plat book
Whether a current Hancock County edition exists varies, so ask locally in Bar Harbor before ordering; county offices often know if one is in print. Older editions are useful for family history around Aurora, showing who held a farm decades ago.
Reading a Hancock County atlas page
Plat book pages for Hancock County generally include an index of owners, so you can track down a family name near Ellsworth without knowing the township. Acreage printed in a county atlas is approximate; the deed and a licensed survey decide the real figure for a tract around Ellsworth. If you use a plat book for hunting permission near Brooksville, recheck the landowner on the county map first.
Editions, deeds and printouts
Names in an older Hancock County atlas can lead you to the right deed in the grantor-grantee index for land near Bucksport. If you can't track down a printed edition, a screenshot of each township from the county map works as a decent homemade atlas for the area around Blue Hill.

Fishing, hunting and trapping and scenic and sightseeing transportation make up an above-average share of Hancock County businesses, a clue to how land around Brooklin gets used.
