Ngram Viewer is a search tool that students can utilize to explore the usage of words and names in books published in between 1800 and 2019. The Ngram Viewer reveals users a chart illustrating the very first look of a word or name in literature and the frequency with which that word or name appears in literature because 1800. The Ngram Viewer will let you compare the usage of multiple words or names in one chart.

The Ngram Viewer will let you compare using multiple words or names in one chart. The example that I give up this video is to compare making 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 begin to appear more often around 1890, have a lull in the 1940s and 1950s, and then appear more often once again in the 1960s..
Ngram Viewer is based on books indexed in Google Books. That is why below every chart produced by Ngram Viewer you will find a list of books about each of your search terms. Those books are organized by date..
A third component of Ngram Viewer to keep in mind is that it deals with several languages consisting of English, French, Chinese, German, Italian, Russian, Hebrew, and Spanish..

Applications for Education.
As I discussed in the video above, the Ngram Viewer can provide a great way to start a research activity for trainees. Have them enter a few words then examine the graph to recognize peaks and valleys in the frequency of the words usage. Then inquire to attempt to identify what would have caused those words to be used more or less regularly at various periods in history.
