Google’s N-Gram Viewer is a wonderful and under-appreciated thing: At the click of a mouse, it lets you search Google Books’ huge corpus of material for specific words and combinations of words. This N-Gram analysis, for example, maps the mention of ten different cities in every book written between 1800 and 2000, charting the wax and wane of famous metropolises in the popular consciousness.
