The Kramerius 3 digital library contains Czech monographs and periodicals from the 19th and 20th centuries. It is currently no longer being added to.
The Kramerius 3 digital library contains the full texts of Czech periodicals and monographs from the 19th century and part of the 20th century, digitised mainly within the framework of the Kramerius National Programme until 2011. This is an older version of the digital library. Since 2012, no new digital documents have been added, and the content is gradually being transferred to the modern interface of the *National Digital Library*. To view documents, the DjVu format plugin must be installed on the user's computer; Kramerius 3 does not support remote access in out-of-commerce works mode. Only public documents with expired copyrights are available remotely; copyrighted documents can be viewed from selected computers in the *Study Rooms of the NLCR*.
