Abstract: One or more techniques or systems are disclosed for allowing a first user to control what information is available to other users in the first user's address book on an address book system. A first user can import user contacts from one or more devices into the first user's address book in an address book system. The first user can enter additional contact information data into the first user's address book and edit preferences for other users to view selected portions of the entered contact information. The first user may subsequently identify a second user of the address book system and make a connection with the second user. The first user can edit access preferences for the second user, with regards to the second user accessing the first user's contact information.
