What are biblionumbers and how to find them
What is a biblionumber?
Biblionumbers are unique numbers automatically applied by Koha to bibliographic records created on the system. These numbers are assigned as title records are created and cannot be edited from within the Koha application. The function of a biblionumber is to act as an identification number for a title record.

Reports
There are many different reports that can bring back the biblionumbers on records. A basic setup would be:
SELECT biblionumber, title
FROM biblio
LIMIT 10
This report will bring back results similar to the image below:
This basic report can be limited in an almost unlimited number of ways, including by a specific title, collection codes and date added to the site.
As all title records will have biblionumbers an unlimited report should not be run as the resources used to bring back the result might slow the system.
For assistance in creating a report to bring back a specific biblionumber, please check our support site or contact Interleaf Technology directly.
