Of course, I was speaking of the librarian interface only, not of the opac.
The javascript && ie5+/netscape6 is needed for improved ergonomy, to 
avoid server calls when possible.
You can see in marc acquisition.simple system why we need them :
* client side verif of mandatory values
* 10 tabs, hidden and shown through javascript too. I Could not do this 
under nn4, even with javascript.

I agree about the necessity to re-check on server side the values sended 
in a form, but to be honest, without javascript, marc biblioadd won't 
work at all :-\, so I presumed it's on. I agree it's not a good thing/
