Bernadette Houghton frames digital preservation as an intrinsically unstable and interventionist practice in which the preservation of digital artefacts depends not merely upon retaining files, but upon sustaining the technological, legal, and organisational ecologies that make those files legible over time. Her central argument is that digital preservation differs fundamentally from analogue custodianship because digital materials are shorter-lived, infrastructurally dependent, and demand continuous curatorial action rather than passive storage. This transforms preservation into a mode of anticipatory governance, requiring institutions to make resource-intensive decisions under conditions of uncertainty about future technological relevance, cultural value, and access requirements. Houghton’s most compelling intervention lies in her insistence that metadata is the indispensable substrate of preservation: without robust descriptive, structural, and provenance metadata, digital objects may survive materially yet become functionally irretrievable, epistemically opaque, and archivally meaningless. She thus elevates metadata from technical supplement to ontological condition of archival existence. This argument is deepened through her analysis of multiplicity, wherein born-digital objects proliferate across platforms, versions, and formats, destabilising notions of originality, authenticity, and preservation master copies. Simultaneously, Houghton demonstrates that preservation is constrained by the combined pressures of software obsolescence, proprietary formats, legal restrictions, and privacy obligations, each of which complicates long-term access and may require institutions to preserve not only content, but also the software, hardware, and execution environments that render it intelligible. Particularly incisive is her claim that preservation may itself entail juridical contradiction, as acts of migration, emulation, or duplication can infringe copyright even while enabling cultural continuity. Her conclusion is therefore neither technocratic nor deterministic: digital preservation is best understood as a strategic exercise in informed uncertainty, where institutions must make provisional yet consequential decisions about what future publics will be able to know, access, and remember.
