=head1 NAME
=head1 SYNOPSIS
- use C4::Scan;
- &ImportBreeding($marcrecords,$overwrite_biblio,$filename,$z3950random,$batch_type);
-
- C<$marcrecord> => the MARC::Record
- C<$overwrite_biblio> => if set to 1 a biblio with the same ISBN will be overwritted.
- if set to 0 a biblio with the same isbn will be ignored (the previous will be kept)
- if set to -1 the biblio will be added anyway (more than 1 biblio with the same ISBN
- possible in the breeding
- C<$encoding> => USMARC
- or UNIMARC. used for char_decoding.
- If not present, the parameter marcflavour is used instead
- C<$z3950random> => the random value created during a z3950 search result.
+ Z3950Search($pars, $template);
+ ($count, @results) = &BreedingSearch($title,$isbn,$random);
=head1 DESCRIPTION
- ImportBreeding import MARC records in the reservoir (import_records/import_batches tables).
- the records can be properly encoded or not, we try to reencode them in utf-8 if needed.
- works perfectly with BNF server, that sends UNIMARC latin1 records. Should work with other servers too.
