As research libraries continue to expand the scope of content they acquire, manage, and make accessible, the preservation charge within organizations is broadening. Libraries and other cultural heritage institutions must balance the preservation of books, manuscripts, archives, and audiovisual materials with born-digital and digitized content. As preservation challenges and strategies evolve, professional positions in preservation must also evolve to meet the needs of academic and other cultural institutions. The ability to quantify how preservation positions are changing, and to identify the required skill sets and educational backgrounds needed for preservation professionals, is central to navigating this shift. To begin to address this, the authors collected and analyzed announcements for professional preservation positions in libraries and archives from 2004 through 2015. They compared the contents of announcements between earlier and more recent years to identify potential trends in preservation employment.
