A Harrison County plat book is the township-by-township atlas farmers, hunters and land buyers around Pass Christian have kept in the truck for generations. This guide covers finding a printed edition for Harrison County, Mississippi, and using the free parcel map in the meantime.
How to use the Harrison County plat book
Private publishers compile plat books from county records, so a county edition is a snapshot of who owned land near Biloxi the year it was printed. Don't confuse it with a subdivision plat on file for lots in Pass Christian; that recorded plat is a legal document, while the atlas is a reference.
Search Harrison County parcels by owner, address or ID
The county's own public map is the Harrison County parcel viewer, and it opens without an account for parcels in Pass Christian and the rest of the county.

Current and older editions
Try the library in Biloxi or a local historical society for older Harrison County editions; libraries sometimes keep past atlases for reference. Collectors and genealogists prize old Harrison County atlases because they display farm names and owners near DeLisle long before online maps.
Atlas details and limits

Acreage printed in a county atlas is approximate; the deed and a boundary survey decide the real figure for a piece of ground near Gulfport. For a land purchase near Gulfport, rely on the county parcel record and a title search, not an atlas.
Making your own atlas of Harrison County
