Einwohnerkartei Hannover 1700-1850

[hjb]

Is there are key to the Einwohnerkartei for the city of Hannover, available on FamilySearch at https://www.familysearch.org/search/cat ... %20Library? I have a couple of images from the database saved but am not sure I am understanding all the abbreviations correctly.

Thank you!
