Some history here :
Katipo & HLT, when developping the 1st version of Koha defined 3 level 
for a given "book".
The biblio, the biblioitem, the item.
* The biblio : it's what is unmovable. Like the title & the author. For 
example "les fleurs du mal" from "Baudelaire"
* The bibliotem : it's what changes on various edition. For example 
"Edition 1960, in 20x10cm size" and "edition 1980, in pocket size".
* The item : it's what refers to the "real" item you have. For example, 
you have 2 items for the biblio "les fleurs du mal, edition 1960, 
20x10cm" : one acquired in 1990, page 10 missing, barcode 1234, and one 
acquired in 2001, barcode 4321.

HOWEVER : in MARC, the 3 level DOES NOT EXIST. There are only 2 : the 
biblio level and the item level.
So, in 2.0 and later versions, biblio & biblioitems ARE MERGED. There is 
a 1-1 relation between both. In fact the biblioitems table could 
disappear, but nobody taked care of this until then.
(look at DB schema, DL from www.koha.org/wiki)

Right for OPAC.
In intranet, the "default" templates in the 2.2 version will be 90% css 
based. Only a few silly html code will remain.
It's simple CSS however.
