Google Adds Glossary and Stock Quote Links
From the Google Weblog, news that Google has incorporated a glossary feature:
Use "define" along with a search term to retrieve a web definition - example: define habeas corpus. At the end of the definition, you will see the phrase "More definitions," which will provide you with a list of definitions from a range of website sources.
In addition, searches for specific companies include a link to related stock quotes.
