We’ve been adding new apps to the Google Apps Marketplace every week since launching in March, but today are happy to bring you 16 new apps in a single day. These apps, like all installable apps in the Marketplace, offer single sign on with your existing Google Apps user accounts, so there are no new user names or passwords to manage. Beyond single sign on, many offer deeper data integration with Google Docs, Gmail, and Google calendar to help users work more efficiently, regardless of which app they happen to be using to get their job done.

As a Google Apps administrator, once you install and evaluate an app, you can deploy it to your users in only a few clicks. (watch how this works)
