In the late 1960s, Mario Alinei created Spogli Elettronici dell'Italiano Contemporaneo, an academic analysis of Italian literary masterworks (including Calvino's Il sentiero dei nidi di ragno). Now, Google can do Alinei's work in a few seconds; on Google Books overview page, you'll find a cloud of "Common Terms and Phrases". This cloud represents the distribution of words in a book: big terms are more common in the book, while small terms are rarer. As with the other features on the Book Overview page, the word cloud is meant to offer a new way to explore our catalog.
