Google introduces Web History

Web History, a new feature for Google Account users that makes it easy to view and search across the pages you've visited. If you remember seeing something online, you'll be able to find it faster and from any computer with Web History.

The new feature requires a Google Account and the Google Toolbar with PageRank enabled. The Toolbar, as part of your browser, helps Google to associate the pages you visit with your Google Account.

If you're currently a Search History user, you'll notice that Google has renamed Search History to Web History to reflect this new functionality.
