Excerpt
Executive Summary: Goddard Space Flight Center (GSFC) relies increasingly on electronic means to record and disseminate information about its missions, activities and operations. The mission of the Library is to preserve and provide access to the knowledge assets needed to carry out the Center?s mission, and preservation of the GSFC?s digital assets are a natural outgrowth of the GSFC Library?s current activities. Therefore, the GSFC Library conducted a project to evaluate the environment for digital preservation at GSFC and to develop a framework for preserving GSFC digital assets. Two types of resources were emphasized during this pilot project. The first is the video capture of colloquia, mini-courses, and other activities in which internal and external experts share the results and lessons learned from projects. This has been identified as a key component of the GSFC Knowledge Management initiative. The second pilot captured Web sites, with an emphasis on project Web sites and those from directorates that conduct scientific and technical research and engineering activities...
