Hello all,
 
one more question, I'm trying  to understand the purpose of the follwoing tables and how they comunicate :
 
1. Biblio
2. BiblioItems
3. Items
 
It's confusing, because first I though BiblioItems table is for books only, but when i added a CD/DVD item it was entered in the BiblioItems.
 
but not added to the items table until I add another Item within this CD/DVD..
 
Can anyone clarify how they work together
 
Regards,
Musab
