Librarians and Google share a mission: to organize the world's information and make it universally accessible and useful. We support librarians like yourself who work each day to further that mission. This page is a first step toward improving and expanding that support.
Keep up to date with Google.
In the next few months, we'll be launching a newsletter that will go out four times a year — just for librarians. Subscribe now to receive Google tips, news of new features, and other information relevant to you.
Followup - after subscribing you'll be taken to a Google Groups page - right now there are 179 members in this group, and I haven't seen this before, but you can get RSS feeds of the messages posted to this group, so I guess you don't even have to give Google your email address for the newsletter - the RSS feed for the latest 100 messages is here. (right now there's only one message in the group; an introductory one).
