Google Notebook
NOTE: The Google Notebook service and API are being discontinued as of January 2009. This API allows client applications to view public notebook content in the form of Google data API ("GData") feeds. Your client application can request a list of notes from a public notebook, request a list of public notebooks owned by a particular user, and query for notes that match particular criteria. Google Notebook feeds are currently read-only and public-only you can't send data to Notebook using the data API, and you can't get a feed of private Notebook data.
