This article explores e-deposit of Namibia’s documentary heritage at the National Library of Namibia and proposes a digital preservation framework for the country’s documentary heritage. The study triangulated the Open Archival Information System (OAIS) Reference Model and the Digital Preservation Capability Maturity Model (DPCMM), which helped to unpack digital preservation concepts. Within the pragmatic paradigm, the study adopted a convergent parallel mixed methods approach and employed a single case study design. The study population consisted of users of the National Library of Namibia, the management of the Namibia Library and Archives Service (NLAS), and board members of the Namibia Library and Information Council (NLIC). Respondents in the quantitative part of the study were selected using a convenience sampling method, while participants in the qualitative aspect of the study were selected using a purposive sampling method. Quantitative data were collected using semi-structured questionnaires, while qualitative data were collected using semi-structured interview guides and a document search guide. The study’s findings revealed that the National Library of Namibia does not have a policy or guidelines to regulate the handling of electronically deposited resources or the harvesting of electronic resources. The study proposes a digital preservation framework for the National Library of Namibia and the Namibia library and information sector. This framework could assist the National Library of Namibia in developing policies and guidelines to regulate the digital preservation of Namibia’s documentary heritage for posterity.
