The amount of documents published on the Internet is growing dramatically – many of them are often changing and others are even being lost. If the documents that have a research value are not archived a considerable part of the national cultural heritage would disappear forever. The responsibility for archiving online-born documents and their registration in the national bibliography is usually assumed by national libraries and/or other deposit libraries.
