OLD - AP English Research Guide: Websites

This is a great tool for hunting down website information from the recent past (from 1996 on) that is no longer maintained on the web. The Internet Archive uses web crawlers to take selective snapshots of a wide array of websites and stores them for review even after the sites have been taken down by their original hosts. Note that it only covers a sampling of sites, and the frequency of snapshots is sporadic, so you will not always find what you're seeking.

When you enter phrases into the Google Books Ngram Viewer, it displays a graph showing how those phrases have occurred in a corpus of books (e.g., "British English", "English Fiction", "French") over the selected years.
