Here’s a list of Z39.50 servers to add to your integrated library system such as Koha. Z39.50 servers are incredibly useful if you want to copy catalogue. We advise that you add multiple servers (at least 3-5) with high quality bibliographic data. We recommend adding the Library of Congress and British Library as part of your target servers – not only are these some of the biggest libraries in the world, guaranteeing that you will find most of the records you need there (the Library of Congress is actually the biggest library, based on item count and budget), but you can be sure that the bibliographic and authority records you retrieve from them are of the highest quality possible.
Some of these servers (such as the British Library) may require authentication – so you may need to contact them to ask for a username and password in order for you to be able to access the servers. Click here to download the file
