Library: A Collaborative Documentation Site
Existing pages feature a convenient link that enables quick access to the Google Docs interface for any particular document, and editing the Google Doc makes changes to the page in Library. Using Google Docs as the editing interface for Library helped us create a living repository of documents, how-tos, tips and guides that everyone could contribute to. Instead of just showing a list of links to Google Docs, Library provides a clean interface for viewing and navigating between those documents.
