Google Hacks

Google Hacks is a compilation of carefully crafted Google searches that expose novel functionality from Google's search and map services. For example, you can use it to view a timeline of your search results, view a map, search for music, search for books, and perform many other specific kinds of searches. You can also use this program to use 'google' as a proxy.
