The article discusses some specialty subdomains of digital preservation such as electronic-journal archiving and Web archiving. The preservation of scholarly online journals presents special organizational and technical challenges. Technically, the source for electronic journals can be anything from images of printed pages to highly marked-up text in XML or SGML. The Portico archive is a centralized preservation repository of scholarly electronic journals. Most Web archiving is either site-centric, topic-centric, or domain-centric. One of the best ways to keep current in Internet archiving developments is to follow the annual International Web Archiving Workshop, which makes all papers and presentations freely available on the Web.
