Quantitative Analysis of Culture Using Millions of Digitized Books
"( We constructed a corpus of digitized texts
containing [5 million books]
about 4% of all books ever printed.

Analysis of this corpus enables us to investigate
cultural trends quantitatively.
We survey the vast terrain of "culturomics",
focusing on linguistic and cultural phenomena
that were reflected in the English language
between 1800 and 2000.
We show how this approach can provide insights about
fields as diverse as lexicography,
the evolution of grammar, collective memory,
the adoption of technology, the pursuit of
fame, censorship, and historical epidemiology.)
