The London Archives’ Journey to Modern Cultural Asset Management and Digital Preservation

The London Archives, London

Preserving London’s Past, Protecting Its Future with Cultural Asset Management

Introduction

The London Archives (TLA), one of the UK’s most important free public archives, that has a singular and ambitious focus: providing access to and the preservation of London historical artifacts from 1067 AD to the present day. With millions of historical manuscripts, maps, photographs, books, films and TLA-specific research guides, along with exhibitions, events and workshops, TLA provides an exceptional visitor and research experience for the public, historians, genealogists, academics and cultural institutions worldwide.

 

Meeting the Needs of a Modern, Large‑Scale Public Archive 

To safeguard the city’s historical memory and support the accessibility and findability of over 3 million collection records, TLA had these key requirements:

  • A reliable, enterprise-scale archival system capable of managing millions of records over time without degradation
  • A flexible, customizable architecture able to keep pace with evolving archival standards and increasingly complex collections
  • Standards-based metadata support, including consistent use of ISAD(G), to ensure long-term data usability and interoperability
  • Tools to support high-demand public research services, helping staff process over 120 daily researcher requests (more than 43,000 per year) efficiently

Key Outcomes

Celebrating 20 Years of Archives Reliability and Growth

Since selecting MINISIS Archives in 2006 (now provided by Soutron Global), The London Archive has benefited from a proven foundation for managing an increasingly complex collection.

“We have found MINISIS Archives to be reliable, easy to search and expandable to handle our growing collection size and customization requirements. We’ve never needed to look for an alternative solution.”

In fact, in the 20 years following implementing MINISIS Archives, TLA has seen their collections grow exponentially from 3 million records to over 6 million records. Handling a dataset of this magnitude requires more than just storage; it requires a robust architecture capable of maintaining high-speed searchability and data integrity, which MINISIS Archives consistently delivered. 

However, as the collection grew, so did the complexity of the formats involved, with some formats becoming obsolete, making database backups insufficient to ensure continued accessibility of their collection materials. TLA recognized that backups alone were no longer sufficient to safeguard digital materials long-term from format obsolescence.

Adding a Trusted Digital Repository: Obsolescence Protection with Digital Preservation

Born‑digital historical materials require proactive long‑term preservation to protect against digital degradation ensure ongoing accessibility of digital items and their contextual metadata, TLA implemented the MINISIS Trusted Digital Repository (TDR) in 2019.

After implementing MINISIS TDR for their digital preservation solution, TLA gained:

  • An OAIS standards-based preservation environment that ensures authenticity, integrity, and long-term accessibility of digital assets
  • Protection from software and format obsolescence
  • Secure, redundant storage and replication beyond database backups
  • Automated fixity checking to maintain data integrity and protect against data loss
  • Preservation workflows aligned with international best practices and standards

This ensures both born‑digital items and digitized surrogate materials remain authentic, accessible and understandable for future generations.

 

The Next Generation: Reimagining Archival Stewardship for the Digital Era

How The London Archives is Preparing for the Future

To ensure these irreplaceable artifacts remain accessible to researchers and the public, TLA has partnered with Soutron and MINISIS and is in the process of transitioning to a next-generation web-based Cultural Asset Management System (CAMS), capable of managing archives, library and museum collections within a single, modern platform.

  • Improved anywhere access for staff 
  • A single, unified search across all collection types 
  • Enhanced discovery experiences for visitors 
  • Elimination of siloed databases 
  • A deeper, more interconnected presentation of London’s history

The web-based architecture of their new solution will improve accessibility for staff and supports richer discovery experiences for researchers, because unlike traditional siloed databases, now TLA visitors will be able quickly use a single search deliver results from multiple collection sources, helping to present a more complete, interconnected picture of London’s history.

Standards-based Large-Scale Data Migration

During our interview with Nicola, she shared how TLA is successfully handling one of the largest cultural heritage data migrations in the UK.

Migrating over 6 million records is complex, but TLA’s success is driven by these migration success factors:

1. Consistent use of ISAD(G) standards: Using structured, standards-based metadata ensures predictable mapping and smooth transformation into CAMS.

2. Deep expertise from the MINISIS / Soutron data migration team, which includes:

  • Detailed data auditing and quality analysis
  • Field mapping aligned to archival standards
  • Iterative validation and testing
  • Secure, integrity-focused transfer processes
  • Full preservation of relationships, hierarchies, and contextual metadata

Nicola describes the process as “pain-free,” complimenting the team’s ability to maintain accuracy, searchability and contextual integrity throughout the migration.

Supporting High-Demand Research Services

With over 120 researcher requests daily, the MINISIS platform enables TLA to efficiently deliver high‑quality public services.

TLA receives more than 120 researcher requests every day. The MINISIS platform helps streamline this high service volume by providing researcher-focused tools, including:

  • Online catalogue (OPAC) search – (Access the live Catalog)
  • Bookmarking items for future reference
  • Revisiting previously viewed documents
  • Requesting and reserving items for on-site use
  • Sign-up for a free TLA History Card to access original materials in the Archives Study Area

These services maximize researcher efficiency and ensure a smooth, predictable experience for visitors while providing TLA staff the tools they need to efficiently service over 43,000 requests per year.

Looking Ahead: Building a Future‑Ready Archive

The London Archives’ Innovation in Cultural Asset Management and Digital Preservation

As TLA advances their usage of CAMS, they are set to unlock even more digital stewardship functionality. The team is looking forward to:

  • Streamlined accessioning workflows 
  • More detailed provenance tracking 
  • Tools for exhibition planning, loans and collection management

Together, MINISIS CAMS and the MINISIS Trusted Digital Repository provide TLA with a future-ready ecosystem, one that supports operational efficiency, public access and the long-term preservation of London’s documentary heritage, ensuring that the story of London. Fom the Norman Conquest to the digital 21st century, remains preserved and accessible for generations to come.
