Social Tagging for Archival Collections explored the inclusion of user-generated tags to make the information in archival collections more discoverable. Because most archival finding aids do not provide comprehensive information their contents (for example, information is provided about a box or folder, but not necessarily about each item inside), social tagging shows promise as a tool to offer more in-depth information about these collections not only researchers, students and faculty, but also to archivists, librarians, and curators working with them. This project was challenged by technological limitations of fully integrating a tagging function into the current generation of archival systems, but the concept showed promise for future development as systems evolve.
