Ngram Viewer is a search tool that students can use to explore the usage of words and names in books published between 1800 and 2019. The Ngram Viewer reveals users a graph highlighting the first look of a word or name in literature and the frequency with which that word or name appears in literature given that 1800. The Ngram Viewer will let you compare the usage of several words or names in one graph.

Googles.
Ngram Viewer is a search tool that students can utilize to check out the usage of words and names in books released in between 1800 and 2019. The Ngram Viewer shows users a graph highlighting the very first look of a word or name in literature and the frequency with which that word or name appears in literature since 1800. The graph is based on the books and periodicals that are indexed in Google Books.

By the method, the book that I pointed out in the video is That Wild Country by Mark Kenyon..

The Ngram Viewer will let you compare using several words or names in one chart. The example that I offer in this video is to compare the use of the terms “National Parks,” “National Forests,” and “National Forest Service.” By looking at the Ngram Viewer for those terms I can see that they start to appear more frequently around 1890, have a lull in the 1940s and 1950s, and then appear more frequently again in the 1960s..
Ngram Viewer is based on books indexed in Google Books. That is why listed below every graph generated by Ngram Viewer you will discover a list of books about each of your search terms. Those books are organized by date..
A 3rd element of Ngram Viewer to note is that it deals with several languages including English, French, Chinese, German, Italian, Russian, Hebrew, and Spanish..

Applications for Education.
As I pointed out in the video above, the Ngram Viewer can provide an excellent way to begin a research activity for students. Have them go into a few words then take a look at the graph to identify peaks and valleys in the frequency of the words use. Ask them to try to identify what would have caused those words to be used more or less regularly at different durations in history.
