I wrote a reply yesterday and didn't check it went to the list. Here's my explanation for everyone The item number is the number that identifies the book -- I thin librarians call this the self list number. Biblio is the overall grouping of all titles. E.G. C.S. Lewis, "The Lion the Witch and The Wardrobe" Biblioitem is the edition level E.G. Hardback, paperback, big print version, special leather bound version. The biblioitem number and the biblio number are simply unique keys for database relationships. This works well for reservations. When I designed the reservation system I designed it so that a person could reserve "The Lion, the Witch and the Wardrobe" and get the first available copy, or could specifically request the large print version.

We're just starting out with Koha 2.0 to see if it could be used as a replacement for Follett. However, we are running into a few snags that should be fairly simple to fix.
Our major snag is lack of documentation for the internals of Koha. For instance, is there a description of the various database tables, and what each field is used for? This would make mapping fields to MARC fields much simpler. We're running into problems with our mappings, especially with the distinction between items and biblioitems, for instance.
Is this kind of low-level documentation available anywhere??
