*) Aleph's OAI-PMH implementation follows the specifications available from http://www.openarchives.org/OAI/openarchivesprotocol.html with a single exception – individual records cannot be retrieved using the "GetRecord" function.

The XML files are not intended for direct reading by humans but for further machine processing. Their size is considerable; therefore, we do not recommend trying to open them directly in the web browser (and also avoid trying to open them on mobile phones and similar devices). Instead, first you should save them to your disk (usually using your right mouse button and selecting "Save Link As" or a similar option). Then you can decompress the downloaded files and save them with an XML extension. The file sizes mentioned above are those reflecting the decompressed files.

Files for download are generated from current data once a week (each Monday).

Although the datasets are available under a CC0 license, you can consider mentioning the National Library of the Czech Republic as a source of data for your project.

Information on our datasets can also be found on the Czech National Open Data Portal and on the data.europa.eu portal.

If you wish to learn more about our activities related to opening data, feel free to have a look at a list of publications and presentations on this topic and an overview of our collaboration with Wikidata.

Please also consider sharing with us – via a webform – how you have used the data and provide your feedback.
