I would use a grid based on an updatable view with the ISBN as a parameter. For each new book, you requery the view.

>I have a form on which I'll have two files in the data environment. A book file and an author file. An author is related to the book by an ISBN number. One book can have several authors.
>
>On the title entry form I'd like to show all the authors (lastname) for a particular title (maybe in a listbox). The user would have the ability to add/delete authors.

>What is the best way to implement this on a form (listbox?,grid?) How do I only show the authors that belong to that book?
