The Society of Antiquaries of London’s collection of one hundred and seventy historical printing plates, dating from the early eighteenth to mid-nineteenth centuries, has long been a hidden gem. This paper presents the results of a research project initiated in 2022, focusing on the provenance, manufacture and bibliographical use of these plates. It explores the evolution of printing practices and the role of coppersmith stamps, shedding light on production methods and industry connections. The project involved digitising the plates for improved accessibility and preservation and cataloguing efforts to establish standardised guidelines for similar collections. Furthermore, the study uncovers the Society’s historical interest in maintaining and utilising these plates, providing valuable insights into past printing practices and collection management. This research enriches our understanding of the Antiquaries’ holdings through meticulous investigation and documentation and underscores the significance of exploring overlooked aspects of historical collections. It also calls for future research endeavours and collaborations to explore connections within the Society’s collections further and expand our knowledge of printing history. Overall, this study emphasises the importance of preserving and studying printing technology as valuable artefacts that contribute to our understanding of the past.
