The A–Z or A to Zed, 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 currently produced by Geographers' A-Z Map Company Limited. 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.
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:
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).
