Go to the PROB 6 class lists in Bookcase 4 and look up the year of administration to identify the relevant PROB 6 volume number. Take the numbered black marker box from the shelves in the Census Reference Area and note the number on the box. This number will be your seat number. Go to the microfilm cabinets in Area A and take out the PROB 6 film you require and put the marker box in its place. There are sub-sections within each month so a thorough check is needed.
Entries are in latin, but follow standard forms.
Note the full reference. Take the rewound film to the Copy Desk or go to any of the self-service copiers located around the edge of the reading room and in the Wills room.
