It can be also used to make other types of documents accessible, such as maps, sheets of music, or old prints, if need be parts of documents, such as articles or chapters. The system is even suitable for „born digital“ documents, meaning those that come up in electronic form. The Kramerius system is being updated continuously, so that its metadata structure corresponds with the standards published by the National library of the Czech Republic.
