The lot location maps series consists of three boxes of index cards that have hand-drawn maps of specific lots and the lots' immediate area within Green-Wood Cemetery. The lots are drawn to show their proximity to cemetery roads, monuments, fences, and other structures. This series is in numerical order according to lot number and many cards contain contact information for the lot owners.

Box 3 has a “No Lot #" and an "Estate Information" section for index cards without maps or lot numbers. These index cards are organized alphabetically by name and contain addresses and remarks regarding unidentified lots.

The lot diagrams and contact cards with lot numbers are arranged in numerical order by lot number.

The contact cards of lot owners and estate contact cards without lot numbers are arranged in alphabetical order by the surname of the lot owner.
