Hi Pierre, You might want to take a look at another open source project - http://reportman.sourceforge.net/. I've used it successfully for generating reports against Koha's MySQL database. It even does barcodes. I think the above project is similar to Crystal Reports or ReportSmith that Trevor mentions. I run it as a totally separate program from Koha, connect to the Koha database and generate my report. I'm not sure what rssKoha is. If what you are suggesting would integrate into Koha, I think that would be a better approach. Rob
