Ngram Viewer is a search tool that students can utilize to check out the use of words and names in books published between 1800 and 2019. The Ngram Viewer shows users a chart 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 Ngram Viewer will let you compare the use of numerous words or names in one graph.

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 the usage of the terms “National Parks,” “National Forests,” and “National Forest Service.” By taking a look at the Ngram Viewer for those terms I can see that they start to appear more often around 1890, have a lull in the 1940s and 1950s, and after that appear more frequently again in the 1960s..
Ngram Viewer is based on books indexed in Google Books. That is why below every chart created by Ngram Viewer you will find a list of books about each of your search terms. Those books are organized by date..
A 3rd component of Ngram Viewer to note is that it deals with several languages consisting of English, French, Chinese, German, Italian, Russian, Hebrew, and Spanish..

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

Googles.
Ngram Viewer is a search tool that students can use to check out the usage of words and names in books released between 1800 and 2019. The Ngram Viewer shows users a graph illustrating the very first appearance of a word or name in literature and the frequency with which that word or name appears in literature because 1800. The graph is based upon the books and regulars that are indexed in Google Books.

Applications for Education.
As I mentioned in the video above, the Ngram Viewer can offer an excellent way to start a research study activity for trainees. Have them get in a few words then take a look at the graph to recognize peaks and valleys in the frequency of the words usage. Ask them to try to determine what would have caused those words to be utilized more or less regularly at different durations in history.
