Hi Steve

There is a one to many relationship between biblio and biblioitems.
One biblio can have many biblioitems, which in turn can have many items.

So the way it works, is that a biblio has data like title, author, subject
attached to it.
A biblioitem has data like ISBN number, Dewey number, Class
Then an item has purely item specific data, like last seen, accessiondate,
replacement price etc.

For example
http://hlt.katipo.co.nz/cgi-bin/koha/detail.pl?type=intra&bib=1461&title=David%20Copperfield

David Copperfield, 
This has one biblio, 3 biblioitems, and 4 items.

Hope this helps to explain it

Chris
