A brief description of each book, entitled “About the Book,” gives some rudimentary additional information, including a list of the words and terms that appear with most frequency in the book. It sometimes provides links to buy the book online and identifies libraries where the book can be found. The search tool permits a researcher to identify those books, out of millions, that do, as well as those that do not, use the terms selected by the researcher.

The Google Books search function also allows the user a limited viewing of text. In addition to telling the number of times the word or term selected by the searcher appears in the book, the search function will display a maximum of three “snippets” containing it. A snippet is a horizontal segment comprising ordinarily an eighth of a page. Each page of a conventionally formatted book in the Google Books
