Since you are making an address book and not a person book I would start out by making a simple list of addresses. Each address could have a "person" or a "name" field. You could then sort your list by the name of each person associated with each address. If an address has no person associated with it then you put it at the beginning (or end if you want) of the list. I think this would most closely mimic how a rolodex works. It doesn't really matter if you implement it as a list of dictionaries or a list classes I believe they would be equivalent in this case. tim -- http://mail.python.org/mailman/listinfo/python-list
