If you set Bento to display the Address Book library, Bento gets the contact information and groups from the Mac OS X Address Book application. When you make changes to records in the Bento Address Book library, you are actually updating the records in the Address Book application.
You can use the Bento Address Book library to edit data from any application or device that synchronizes with the Address Book application.
By displaying the Bento Address Book library, you add your contacts to Bento and keep your contacts up-to-date, whether you edit the information in the Address Book application or in Bento.
If you delete a collection under the Address Book library, the associated Address Book group is deleted also. Similarly, if you delete a group in the Address Book application, the associated collection under the Address Book library is deleted also.
You can use the records in the Bento Address Book library just like the records in any other library and collection in Bento. The only difference is that changes in the Address Book library update information in the Address Book application.
