ARL has released Managing Born-Digital Special Collections and Archival Materials, SPEC Kit 329.
Here's an excerpt from the announcement:
This SPEC Kit explores the tools, workflow, and policies special collections and archives staff use to process, manage, and provide access to born-digital materials they collect. It also looks at which staff process and manage born-digital materials and how they acquire the skills they need for these activities, and how libraries have responded to the challenges that managing born-digital materials present.
