"I have a question about label..." <- I have found this instruction but it is not workin: The Bibliographic Data to Print includes any of the data fields that may be mapped to your MARC frameworks. You can choose from the preset list of fields or you can click on 'List Fields' and enter your own data. In 'List Fields', you can specify MARC subfields as a 4character tagsubfield string: (ie. 254a for the title field), You can also enclose a whitespaceseparated list of fields to concatenate on one line in double quotes. (ie. "099a 099b" or "itemcallnumber barcode"). The fields available are from the database tables list below. Finally you could add in static text strings in singlequote (ie. 'Some static text here.')
