The same day I posted in this space a blog about big data a new book came into the library with my name on it as a reserve about the very same subject.
It's called "Uncharted: Big Data as a Lens on Human Culture," and it is by Erez Aiden and Jean-Baptiste Michel, the two guys who invented the Ngram Viewer that Google now makes available.
I have used Ngram Viewer for research, but was unaware of its background and the sorts of searches being performed by scientists and students of the humanities and mathematics such as Aiden and Michel.
This book is a fascinating look at this important search engine development.
Right now, Google has scanned in about 30 million books of about 150 million available. So Ngram Viewer can only access that number in a word or ngram search. The two authors think all books will be in the database by 2020.
Check out Ngram Viewer by going to Google and searching its apps, or go to Google Books.
