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? I think keeping these all in sync would
be a data maintenance nightmare, since there currently isn't a way to
bulk update the "biblio" level information on all of them in a single

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.

I thought the Advanced Search option was only available for the
biblio-level item types? I meant if I'm choosing to us Item-level
ones, I can't use them for A.S., and therefore I'll make sure to use
CCodes appropriately as a search factor. Note that then I'm **not**
using the item types for my "format" information, just for circ
policies, and don't need these to show up anywhere.

I'm hoping I just didn't make myself so clear. Using the same example:

  Title: Proms 2009 video
  Subjects: Music; Anglophilia
  SomeField: "Disc-VDO + Disc-AVI" (a single string value)

  3 copies of Disc-VDO
  2 copies of Disc-AVI

The member could then choose to check out one disc, or one of each, etc.

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?

This pulls up those tiny icons based on the leader content right? I'm
hoping to not have to get into customizing that. . .
