Hunting for the latest Baltimore County plat book? It's a printed atlas of landownership, usually by township, useful for farms near Towson. Covered here for this county: how the atlas is organized, where to look for printed copies, and how the county viewer fills the gaps, at least around Arbutus.
The Baltimore County plat book: start here
With a lot near Bowleys Quarters, plat books are commercial atlases, that map ownership across the countryside, often organized by township.
Getting to the right map

If you only know roughly where the land is, follow Interstate 70 on the aerial until the lines appear, then click inside the one you want. For acreage around Baltimore Highlands, the parcel card usually lists the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Getting your bearings
Towson holds the county offices, which is where the courthouse records live. You'll also find Arbutus, Baltimore Highlands, Bowleys Quarters, and Carney, where town lots give way to larger tracts. Around 844,703 people call Baltimore County home (Census estimate, 2023) across some 598 square miles. Baltimore County was organized in 1659, which matters when you trace an old farm's title. Features like Chesapeake Bay help you orient on the aerial.
Deeds, plats and who keeps them
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Bowleys Quarters are filed with the Clerk of the Circuit Court (land records). If the land is near Bowleys Quarters, bring the instrument number from the tax record so staff can find the deed fast.
How land is described here
Rural deeds near Arbutus commonly use metes-and-bounds descriptions, listing bearings, distances and landmarks. Platted lots around Baltimore Highlands refer to a recorded plat, making them easier to find. Keep the legal description for land near Baltimore Highlands before you request a deed or survey.

Who handles what

Buying or borrowing a copy

Using the parcel viewer instead

Two kinds of plat
A plat book is not a recorded plat: recorded plats near Arbutus are filed with the Clerk of the Circuit Court (land records), while the atlas is a reference.
A word on accuracy
For a tract near Bowleys Quarters, the acreage figure is an estimate; just a licensed surveyor establishes the real corners on the ground. Around Arbutus, records update in batches, so a deed recorded last month may not show yet.
Why people still buy them
Farmers, hunters and appraisers near Bowleys Quarters use plat books for a big-picture view of who owns what.
Field tips
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Baltimore Highlands, but coverage can be spotty out of town. A saved image of the lot near Chesapeake Bay and its lines helps when you meet an owner or agent.
