In September 2015, the Institute of Museum and Library Services (IMLS) awarded the Council on Library and Information Resources (CLIR) a grant to investigate the early impacts of the National Digital Stewardship Residency (NDSR) programs, in order to inform subsequent development of similar programs by others with a vested interest in building professional capacity to preserve digital information. "Keepers of Our Digital Future" provides a formative evaluation of the early residencies, based on surveys and interviews with NDSR participants and supervisors from the Washington, D.C., New York, and Boston programs. The authors offer a series of findings and recommendations for future programs, noting that as the model is reproduced, there is a greater need for national-level coordination and communication across programs. The following are appended: (1) Study Design and Methodology; (2) Summary and Comparison of NDSR Assessments; (3) Survey Instruments; (4) Interview and Site Visit Protocols; (5) Interview and Site Visit Participants; and (6) NDSR Advisory Board Members.
