Over the past year the University of New Mexico (UNM) Libraries instituted a new digital preservation initiative that was literally built from the ground up. Initially conceived as a means to preserve the libraries' digital collections, the project involved developing program structure, improving tools and working with vendors. As the project developed, the digital preservation needs of a broader community than originally planned became vividly apparent, and it evolved into a much larger endeavor that includes preservation of research data, university archives and digital cultural heritage collections from partner institutions around the state. The presenters will discuss their experiences implementing digital preservation at UNM, and talk about how the initiative is starting to encompass the preservation needs of partner organizations.
