Where to leave it
The line is a count of locations for the United Kingdom, written with a dot. The coordinates are a latitude and a longitude for the London heading, written with decimal points. The bracketed 2299491 is an unlabelled number at the end of the country sentence. The copyright is a year span.
Mixing 13.512 into the latitude, or dropping the dot to make a plain integer the page does not print, would be a different line. The page’s line is United Kingdom: 13.512 locations.
The front page heading is still London. The count says United Kingdom. The note on Edinburgh, Birmingham and Presteigne does not add those three names into this count. The count does not list them.
One phrase, one dot, one label. That is the locations line.
The coordinates are a point for London. The brackets are an unlabelled footer number. The locations line is the one with the word locations.
51.507351 is a latitude. 2299491 is the bracketed footer number. 13.512 is the only one of the three with the word locations beside it.
