2. http://www.webarchiv.cz IIPC 2007 WebArchiv – overview The Czech WebArchiv was originally funded by the Ministry of Culture and launched in 2000. Since then the project has been implemented by the National Library in cooperation with the Moravian Library and the Institute of Computer Science of Masaryk University. Both large-scale automated harvesting of the entire Czech national web and selective archiving are being carried out, including thematic, event-based collections (using Heritrix). Due to copyright law, only restricted on-site access from within the library is possible to all files in the archive (using wayback). Archived resources which are covered by a written agreement with their publisher are accessible online using WERA.
