Well spotted - the quote is wrong, Dr Johnson in 1777 said 'When a man is tired of London he is tired of life'. Well nowadays once that happens, the first stop is Heathrow Airport. Conversely when a woman was tired of life in Sherlock Holmes time, her first stop was Whitechapel.
It is this basis that we use to divide up London into 4 quadrants. A line running North/South through the House of Lords, bisected by a line running East/West following the Thames to the East, and the M4 to the West.
To assist you find the rough location of the UXB's we have also included the A-Z page numbers [in square brackets] for Place names rather than actual locations
