I don't like doing that because I don't want to store the entire name in every other table which needs to be linked with this one. So, for instance, in the table that keeps track of what authors go to what book, I want it to just have two fields, the Book's primary key and the Author's primary key, and I'd prefer those primary keys to be nice and small instead of, say, the entire title and copyright year for the book and the entire first and last name and date of birth for the author. See what I mean? > BTW, Alan Watts is a favourite of mine. Mine too. --Dan ----------------------------------------------------------------------- Daniel G.
