Digital preservation emerges in Bernadette Houghton’s analysis as a domain defined less by technical certainty than by strategic contingency, wherein institutions must preserve not merely digital objects but the shifting ecosystems that render them intelligible. Houghton contends that digital artefacts are inherently more vulnerable than analogue materials because their fragility is compounded by technological dependence: files require active maintenance, compatible software, stable hardware, and often emulated environments to remain accessible. This transforms preservation from passive custodianship into a continuous process of infrastructural intervention. The article develops this proposition through a layered taxonomy of challenges, beginning with the sheer volume of born-digital material, which amplifies every subsequent preservation burden—from storage and automation to appraisal and retrieval. Particularly compelling is the argument that metadata constitutes the epistemic core of preservation: without accurate descriptive, structural, and provenance metadata, preserved files become functionally lost, regardless of their technical survival. Houghton’s discussion of multiplicity—the proliferation of duplicated, versioned, and variably compressed digital objects across platforms—further complicates archival authenticity, rendering the identification of an authoritative preservation master increasingly precarious. Her treatment of software obsolescence and legal constraints deepens the analysis by showing that preservation is constrained not only by technological decay but by copyright, licensing, privacy, and proprietary dependencies that can obstruct migration, access, and emulation. A particularly incisive case is her observation that preserving an object may itself require legal transgression, such as reproducing copyrighted code or circumventing obsolete access controls. Ultimately, Houghton’s central conclusion is that digital preservation is governed by informed uncertainty: archivists do not secure permanence so much as they make disciplined, resource-bound, and necessarily provisional decisions about what future access may still be possible.
