The A–Z, or in full, the Geographers' A–Z Street Atlas is a name given to any one of a range of atlases of streets in the United Kingdom. The first atlas, of London, was originally compiled in the 1930s by Phyllis Pearsall. The company she founded now publishes street maps of many cities and towns in the UK.

[edit] Dating Old Maps

Until quite recently, the maps produced by the Geographers' (A-Z) Map Company did not list their publication date, so dating them can be quite hard. A few things that can help are:

Their first map was published in 1936
There were no maps produced by them during WW2 (1939-1945)
Until 1962, the "Published By" address was 24 Grays Inn Road, Holborn, London
From 1962 to 1992, the "Published By" address was Sevenoaks, Kent
From 1992 onwards, the "Published By" address is Borough Green, Kent
In 1972, the company name was changed from Geographers' Map Company to Geographers' A-Z Map Company

[edit] Cartographic Date

On all their maps, there is a 3 or 4 letter code in one of the corners, often the one containing the key. These letters represent numbers, which are the cartographic date, in the form (M)MYY. There is at least one scheme in use, but possibly also a second.

One scheme is JIHGFEDCBA, for the numbers 1 through 9 and 0, so that HFD would be 357, or March 1957. This seems to be used on all of their maps not in book form (it may be used in the book form ones, but that has not been confirmed).
