But if I use biblio-level itemtypes, and therefore have a duplicate biblio-level record for each format, each one will need to be updated, tagged and listed separately?
Yes, you're right. It would be a nightmare to keep them updated with the same tags and in the same lists.
My Proms 2009 video is available in Bluray, AVI, MPEG, standard DVD and mixed data/vdo DVD. All are exactly the same content, just different presentation/delivery formats.
Other than the item type image issue, using item-level item types is ideal for this.
I thought the Advanced Search option was only available for the biblio-level item types?
No, you can use it for item-level item types.
Now if that **Biblio-level** SomeField has say seven possible values, enforced by Authority, isn't there a way to assign an icon to each value and have this show up in search results? Or failing that, re-purposing an existing field that will at least show the text there?
I don't know of any way to do that. -- Owen -- Web Developer Athens County Public Libraries http://www.myacpl.org
