Aircraft Recognition, subtitled The Inter-Services Journal was a British Second World War magazine dedicated to the subject of aircraft recognition. Published monthly by the Ministry of Aircraft Production between September 1942 and September 1945, the target audience of the magazine was members of all three British Armed Services (Army, Royal Navy and Royal Air Force) as well as members of the Royal Observer Corps.
Less than a year after publication ceased it was recognised that there was a continuing need to study aircraft recognition and the journal was resurrected under the slightly different name of the Inter-Services Aircraft Recognition Journal. In 1950 the name was changed to the Joint Services Recognition Journal broadening its scope to include ships and vehicles as well as aircraft. A final name change took place in 1993 to the Defence Recognition Journal until publication ceased in 2009. (Wikipedia - not altogether accurate information)
