opac-MARCdetail.pl : script to show a biblio in MARC format
|

|
|
=head1 SYNOPSIS
|
|
|
|
=cut
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This script needs a biblionumber as parameter
|
|
|
|
It shows the biblio in a (nice) MARC format depending on MARC
|
|
parameters tables.
|
|
|
|
The template is in <templates_dir>/catalogue/MARCdetail.tt.
|
|
this template must be divided into 11 "tabs".
|
|
|
|
The first 10 tabs present the biblio, the 11th one presents
|
|
the items attached to the biblio
