I like the idea of playing with what the customer/patron will see. The display, that is. Harry Potter is good. But I'd like to suggest a made up creature:
The Furbur Wars by Manifest Work It is part of two series : like the Thomas Covenant series That it has a "The Hobbit" type prequel, not quite in the series, but patrons should be told about it. It can be found bound individually, or included in the entire series. It has the large print, movie (DVD and VHS), talking book ( abridged and unabridged), how the movie was made photograph book.... Many books about the book (literary criticism) Let's try and make this as hard as possible. Once we decide what we should then show the patron/customer who might send a single isbn to OpenFRBR, then we can talk about the DB structure that might do things behind the scenes... What do you think? Kevin
