Koha comes with a tool that will allow you to export your bibliographic, holdings and/or authority data in bulk. This can be used to send your records to fellow libraries, organizations or services; or simply for backup purposes.
At the top of the screen you need to pick what data you're exporting. If you're exporting bibliographic records with or without the holdings information you want to click the 'Export bibliographic records' tab.

Fill in the form in order to limit your export to a specific range (all fields are optional)
![marcexport-pt1]()
-
Choose to limit your export by any one or more of the following options
-
Limit to a bib number range
-
Limit to a specific item type
ImportantThis limit will use the type you have defined in the item-level_itypes preference. If you have the item-level_itypes preference set to 'specific item' and you have no items attached to a bib record it will not be exported. To get all bib records of a specific type you will need your item-level_itypes preference set to 'biblio record'.
