The Google Books Ngram Viewer is a search tool that displays when and how often a term appears in books indexed by Google Books. By using the Ngram Viewer you can discover when a term starts to appear in literature, how often a term appears, and when a term loses popularity in literature. In the video embedded below I provide an overview of how to use the Ngram Viewer.

Thanks to Dr. Lynn Burlbaw at Texas A&M University for sharing some of his Ngram Viewer examples with us earlier this summer at the Practical Ed Tech Summer Camp.
