Are you a librarian or publisher? Take advantage of our bibliographic services to help your organisation give your customers exactly what they want.

Among our metadata services is the British National Bibliography, the most comprehensive record of UK publications from 1950 to the present. You can download weekly updates or monthly files and more for your catalogue, collection development or research.

Use our identifier services to ensure your UK organisation or serial publication is identifiable according to international standards such as ISIL and ISSN.

You can also attend our training for cataloguers. With our courses, you'll be equipped to get the most out of current bibliographic standards. Read our collection metadata strategy and find out how we're going to maintain quality and improve services.
