Liverpool's Duplicate Image Problem: What Happens Next and the Key Decisions Ahead

Liverpool's network of heritage bodies is confronting a long-deferred reckoning over duplicate image replacement — the process of identifying, retiring, and substituting redundant or degraded photographic records held across multiple civic collections. With a city-wide digital infrastructure review now under active consideration at Liverpool City Council, the question of who decides which images stay, which go, and what replaces them is becoming unexpectedly contentious.

The issue has sharpened in 2026 because several overlapping digitisation projects — some dating back to the mid-2010s — are reaching their maintenance deadlines simultaneously. Collections held at Liverpool Record Office on William Brown Street, and at the Merseyside Maritime Museum on the Albert Dock, are among those understood to contain significant volumes of duplicated material. Curators and archivists across the city have been working under interim guidance, but no unified city-wide policy on duplicate image replacement currently exists.

Why the Decisions Matter Now

Duplicate images are not simply a storage nuisance. In heritage terms, they represent sunk digitisation costs, cataloguing labour, and in some cases subtle variations between what appear to be identical photographs — different print exposures, marginal handwritten annotations, or later-generation copies that carry their own historical value. Getting the replacement criteria wrong risks destroying material that cannot be recovered.

Liverpool's collections are substantial. The city's archives hold records stretching back centuries, with photographic holdings covering the late 19th century through to the post-war reconstruction of areas like Everton and the docklands. The concentration of material relating to the Toxteth area alone — including images from before and after the 1981 civil disturbances — makes the question of what counts as a true duplicate particularly sensitive. Archivists at these institutions have previously flagged that automated deduplication software, increasingly used in larger national collections, can misclassify near-identical images as exact copies and schedule legitimate variants for deletion.

National guidance from The National Archives recommends a human-review stage before any irreversible deletion of digitised public records, a standard that Liverpool's institutions are expected to align with. The cost of that review is not trivial: a comparable exercise carried out by Manchester City Archives in 2023 took fourteen months and required dedicated staffing resource across two sites.

The Choices Facing Liverpool's Institutions

Three broad options are now on the table, according to publicly available council committee documentation from the spring 2026 cycle. The first is a centralised replacement programme, coordinating across Liverpool Record Office, the Liverpool Central Library on William Brown Street, and the museum collections managed by National Museums Liverpool. This would pool resource but requires a governance agreement that does not yet exist.

The second option is institution-by-institution discretion, letting each body apply its own criteria and timelines. Critics of this approach point out it risks inconsistency — one archive might retire a duplicate that another would have preserved — and makes cross-collection research harder for academics and community groups using facilities like the Picton Reading Room.

The third path, favoured by some in the digital preservation community, is a moratorium on deletion until a shared metadata standard is agreed. That would preserve everything but kick the problem down the road and does nothing to address the storage cost pressures that partly drove this review in the first place.

A decision point is expected before the end of the third quarter of 2026, with Liverpool City Council's Culture and Visitor Economy committee scheduled to receive a formal options paper. Community heritage groups, including those working in the Granby Street area of Toxteth on neighbourhood history projects, have indicated they want a public consultation stage before any irreversible action is taken.

For residents and researchers, the practical advice is straightforward: if you have a specific interest in images held within Liverpool's civic collections — whether for family history, academic work, or community documentation — the coming weeks are the time to register that interest formally with Liverpool Record Office. Submissions to the consultation process, once opened, will carry weight. The archive is a public asset. The decisions about what survives are, in the end, public decisions too.
