Googol is the name that is given to the number 10¹⁰⁰ (the digit 1 followed by one hundred zeros).

Nine-year-old Milton Sirotta (1911-1981), nephew of North American mathematician Edward Kasner, coined the term in 1920.

The name Google has been derived from the word "Googol" and has been spelled wrong by the founders Larry Page and Sergey Brin (as published in the book "The Google Story" by David A. Vise).

Google makes an extra copy of most of the pages it indexes. Which means if you click on a page and it's not there anymore, often you can get google's copy to read the information that you want, look for the cached link.

The equivalent Search Operator is

• cache:"web page url" (without quotation marks)

If google doesn't have the desired page on file, you may find it in The Wayback Machine
