This work describes the long term preservation of digital documents, particularly websites. The aim of this work is to give an explanation of the long term preservation, to define the differences between various approaches and to describe long term preservation of web content possibilities such as migration or emulation. It also explains risks and challenges of these strategies. It discusses new problems which the long term preservation aim leads to. It also describes possible solutions as well as it describes the situation in selected significant foreign institutions. The main aim of this work is detailed analysis of long term preservation strategy in theNational Library of the Czech Republic, which is the only institution engaged in the preservation of Czech web. The process of data preparation, metadata creation and data storing in the long term repository of the Czech National Library is thoroughly described, including examples and their explanation. Future actions of long term preservation in the Czech Web Archive are articulated in the conclusion. Powered by TCPDF (www.tcpdf.org)

(in English) The topic of the diploma thesis is to compare the WebArchiv with selected foreign Web Archives, which are responsible for preserving the national cultural heritage. The introduction briefly explains the history of Web Archives and typology of harvesting. Next parts deal with the history, legal aspects of archiving, selected types of harvesting, Web resources, systems, accessing and evaluation the Czech (WebArchiv), Australian (Pandora) and British archive (United Kingdom Web Archive). The text continues with an evaluation of the selected archives that mentions strong and weak properties and possible solutions. In conclusion, outlines the problematic aspects of archiving, which must be addressed in the future. [Author's abstract]

This master thesis has examined a user’s capabilities to utilize the Swedish national web archive Kulturarw³ for research purposes. The aim was also to identify any potential areas of improvement in the user’s capabilities working with Kulturarw³. The research questions are: 1. How does Kulturarw³ operate? 2. What are the main factors which affect Kulturarw³ structure and function? 3. What capabilities exist for researchers and students to utilize Kulturarw³ for their research? Are there any potential areas of improvement to the web archives user capabilities? The author has analyzed the web archive altogether using institutional theory in organization studies. The analysis has been loosely structured after Staffan Furusten’s model of the outside world in using institutional theory in organization studies. The purpose of this is to explain why the web archive looks the way it does today. An understanding of the web archive will better illuminate why any potential areas of improvement identified may or may not be possible for KW3 to implement. The author has conducted email interviews, in-person interviews as well as digital interviews with the staff responsible for working with Kulturarw³ at the Swedish National Library, Kungliga biblioteket. A draft of guidelines concerning Kulturarw³ from Kungliga biblioteket and a video-interview at Internetmuseum with one of the the founders of the web archive has also been used as source-material for this master thesis. The author concluded that Kulturarw³ is a national web archive with a long history. Its functions and limitations are complex. Kulturarw³s operation has changed greatly throughout its lifetime because of the surrounding environment. Several main factors which affect Kulturarw³ were identified. Several Swedish laws, international charters and initiatives, collaborations between and relations to other web archives, use of open-source software and digitalization’s impact on Kulturarw³ is discussed in detail. Kulturarw³'s long history of archiving the Swedish web makes it a valuable and plentiful source for research. Its collections and functions should be sufficient for anyone to conduct qualitative research. Yet at the current moment, the web archive is too inaccessible to live up to user’s expectations. That makes it an unviable option for research purposes. Unfortunately, there is not a lot Kulturarw³ can currently change to make it more assessable. The lack of information readily available also hinders users from using the web archive at max efficiency. There is a lot of opportunities for KB to better inform its users of its value and capabilities. An increased collaboration with Swedish research institutions would also benefit both researchers and the web archive in the long run.
