Essex use BDZ for fast loading

“At Essex we use BDS metadata to maintain our catalogue via BDZ as we are z39.50 compliant. The great thing about BDZ and BDS is the responsiveness with which they work and the ability to source records for multiple formats. We request records, both singly and in larger batches, and they are instantly visible in our catalogue. We can definitely say that every penny of our money is well spent on BDS metadata.
Andrew Coburn, Acquisitions & Cataloguing Librarian, Customer Operations – Libraries, Essex County Council


BDZ is the quickest and easiest way to download bibliographic information for records going back to 1950 and an ideal service to bring consistency to your catalogue. It amalgamates the resources of the BDS database, the British Library and the Library of Congress.

Data is sent direct to your library system using the Z39.50 protocol. There is no need to transfer files. Once you have a Z39.50 client, you can access BDZ data from your own workstation seamlessly and without the need for log-in and password.

Search on any of the index terms offered by your system, including ISBN, author, title, keyword and Dewey number.

BDZ is an annual subscription service, and allows unlimited access to an unlimited number of users.

Direct Data Feed

Receive a daily direct data feed of all the work undertaken by BDS each day profiled especially for your library. This service means that your catalogue is always as up-to-date as BDS itself.

You receive a daily feed of information by FTP directly to your catalogue. You can then select and manage this information as you choose.


Autoresponse is a service that allows you to deposit a file of ISBNs on the BDS FTP server, and receive records tailored to your profile within minutes. Autoresponse is an ideal complement to our Direct Data Feed service. It suits libraries who do not have Z39.50 technology, or who require relatively small files of information.

The BDS EDI Model

The BDS EDI (Electronic Data Interchange) model is preferred by libraries using an LMS which does not have the functionality of a Potential Requirements File (PRF) or a Z39.50 client.

The BDS EDI model offers delivery using the library service’s EDI quotes process for items purchased from suppliers. The LMS supplier strips out ISBNs and EANs from the EDI message and then uses BDS Autorepsonse to integrate BDS data into the LMS. This process is conducted hourly at BDS. The BDS EDI model is a streamlined way of accessing BDS data.


BDSLink allows you to enhance your OPAC with the richness of our extended content services.

BDSLink is a comprehensive resource, including cover images and internal scans for books, covers for audio books, DVDs, videos and games, screenshots for computer games, film trailers and audio clips. It covers most of the popular stock you are likely to have in your library.

Images as part of the library catalogue increase the chances of people finding what they want, reducing frustration and enhancing the search experience while increasing lending. That is why the BDSLink is an important resource to keep your library in the public eye.

You can make your catalogue come alive with BDS’s Library Look-up Widget or the BDS Image Grabber service or access the BDSLink via XML API. Using no space on the library server, the images are delivered seamlessly onto the screen of the user directly from the BDS server.

Library Lookup Widget

This easy-to-implement service allows access for your library users, via the OPAC, to all of the enhancements which BDS offers, including cover images, internal image scans, contents information, long descriptions, book reviews, contributor notes, film trailers, games screenshots and audio clips.
The enhancements come straight from the BDS servers direct to your customers and are merged seamlessly on the page when a record is called up.

Image Grabber

Ideal for libraries looking to access the BDS image database to enhance customer experience, this service uses no space on the library’s storage system. Images are sent directly from the BDS servers and merged seamlessly with the data in the library catalogue.


All BDS data and images can be supplied via XML API.
