If you have installed Koha by debian packages, you can use koha-mysql <instance> command in linux shell script like this: biblionumbers = $(echo "select biblionumber from biblio where [your condition]" | koha-mysql) and than you can work variable $biblionumbers, save it in some temporary file and use it as list for export.pl. There should be a parameter to set file with biblionumbers as base for export I think... Josef On Sat, Jan 31, 2015 at 7:25 AM, Giuseppe Angilella < Giuseppe.Angilella@ct.infn.it> wrote:

Hi,

the online export tool for bibliographic records allows to select records in a given range of either biblio number, or item call number, or accession date.

Would it be possible (perhaps via an off-line script) to select records fulfilling other constraints? (Say, a full mysql "where..." condition.)

If not, would it be possible to extract (single) MARC records by off-line invoking export.pl on (single) biblio numbers? (One could have saved a list thereof in an auxiliary file, and then iteratively call export.pl via some script.)

Many thanks in advance.
