Introduction to codes used

In order to list and describe maps on one or two lines, we have encoded certain information on this site and arranged all information in columns. Thus SC is a Standard Cover, p is a paper map and c means the map has a cloth backing.

Column headings
Item No. : For use when ordering.

Sheet No. : As printed on the map, usually top right corner.

Area : Sheet title when available, usually top margin.

Print code : Print codes appear in the brackets after a sheet title (4.12, 3038, 3500/33, A//* and so on). On maps, they are found in either corner of the lower margin. Only the last code is shown in our lists. Within each map series, sheets are in number order and then chronologically by print code or publication date.

Notes : Ownership inscriptions, dates and small labels are not noted.

Date : Publication date of first issue.

Cover : Codes for the major types of cover in any series are explained under the heading in any list. Unless stated otherwise, SC—Standard cover; BK—Book type cover hinged left; BF—Benderfold, single piece cover hinged at the top; HM—Home made cover; pf or cf—paper or cloth folded without covers.

The full list of cover codes can be found by clicking Cover codes.
