historical past. One example is Clio Visualizing History's Click! The Ongoing Feminist Revolution, a web exhibit about the American women's movement from the 1940s to the present. Clio Visualizing History was founded by Lola Van Wagenen in 1996 to meet the growing need for innovative history projects in multi-media platforms. Journalism As existing print publications migrated to born-digital releases, digital native news websites such as HuffPo and Buzzfeed News have grown substantially. This trend toward web-exclusive content has seen the rise of "news applications," or news articles built with interactive features that cannot be replicated on print. "News Apps" are often heavily data-driven, using interactive graphics custom-built for the story by a team of software specialists in addition to the core group of writers and editors. Examples include Baltimore Homicides from The Baltimore Sun, Do No Harm from the Las Vegas Sun, and Snow Fall from The New York Times, which took a team of more than fifteen journalists, web developers, and designers to build. Key Issues Preservation Digital preservation involves the conservation and maintenance of digital content. As with other digital objects, preservation must be a continuous and regular undertaking, as these materials do not show the same signs of degradation that print and other physical materials do. Invisible processes such as bit rot can lead to irreparable damage. In the case of born-digital content, deterioration can occur in the form of bit rot, a process in which digital files degrade over time, and link rot, a process in which URLs link to pages on the internet that are no longer available. Incompatibility is also a concern, in regard to the eventual obsolescence of both hardware and software capable of making sense of the documents. Many questions arise regarding what should be archived and preserved and who should undertake the job. Vast amounts of born-digital content are created constantly and institutions are forced to decide what and how much should be saved. Because linking plays such a large role in the digital setting, whether a responsibility exists to maintain access to links (and therefore context) is debated, especially when considering the scope of such a task. Additionally, since publishing is not as delineated in the digital realm and preliminary versions of work are increasingly made available, knowing when to archive presents further complications. Relevance and Accessibility For digital libraries and repositories that are used as reference materials, such as
