Newcastle City Library and the Hunter Living Histories archive have launched an emergency audit of their shared digital collections after staff identified a systematic duplicate image problem that had gone undetected for at least two years. The issue, confirmed internally this week, affects digitised photographs and documents uploaded to publicly accessible online portals — meaning some records appeared multiple times under different catalogue numbers, while the originals they were meant to replace had been incorrectly flagged as redundant and buried in the system.
The timing matters. Both institutions have been mid-way through a broader digitisation push tied to the University of Newcastle's Hunter Heritage Partnership, a program running since early 2024 that is funding the scanning and online publication of historical records from across the region. With that program entering its final delivery phase before a scheduled December 2026 reporting deadline, any backlog in the catalogue creates downstream problems for researchers, school programs, and community groups who rely on the public-facing collections.
What Went Wrong — and Where
The problem traces back to a batch upload process used at the Laman Street library branch in late 2024. When scanned images from the former BHP Steelworks collection — a tranche of roughly 3,400 photographs donated by the Hunter Valley Research Foundation — were ingested into the Piction digital asset management system, a file-naming convention mismatch caused duplicates to register as unique records. Staff at the library's local history room in the Laman Street building discovered the discrepancy during a routine cross-check in late June 2026.
Hunter Living Histories, which operates its own portal out of the University of Newcastle's Callaghan campus, identified a related but separate problem the same week: approximately 800 images from the Newcastle Morning Herald photographic collection had been replaced by low-resolution proxy files in a 2025 system migration, with the high-resolution originals orphaned in an offline storage folder and effectively invisible to the public catalogue. Staff there are working through the affected records manually.
Neither organisation has published an official incident notice as of Saturday, July 4, but library staff contacted by The Daily Newcastle confirmed the audit is active and that public access to the affected collections has not been suspended. A spokesperson for Newcastle City Council said the council was aware of the issue and working with library staff, but declined to provide a timeline for resolution.
What Researchers and Community Groups Should Know Now
For anyone who downloaded records from either platform between January 2025 and June 2026, the practical advice from library staff is to cross-reference any catalogue numbers against the physical finding aids held at Laman Street. The original analogue card index for the steelworks collection — running to 14 archival boxes — remains intact and is considered the authoritative record. Appointments to view those materials can be made through the library's local history service.
The University of Newcastle's Digital Humanities Lab, which has been providing technical support to both institutions under the Heritage Partnership arrangement, is understood to be developing a deduplication script to automate identification of affected records. That work is expected to take several weeks, pushing some deliverables for the December reporting milestone into a tight window.
The episode highlights a pressure point that has been building across regional archives nationally as institutions rush to digitise before funding windows close. The Hunter region has been particularly active on this front: in 2024, the NSW State Archives allocated funding to digitise flood-risk records in the Lower Hunter, prioritising materials from Maitland and Raymond Terrace that are vulnerable to physical damage. That project also used batch upload workflows of the kind now under review.
For local historians and genealogists — a significant user group for both the Laman Street and Callaghan collections — the immediate disruption is frustrating but limited. Staff at the library's local history room are available Tuesday through Saturday and have been briefed to assist anyone encountering missing or duplicated records. The full audit is expected to conclude by late August.
