The Mills Archive Trust

What The Mills Archive Trust does

The Mills Archive Trust is a UK-registered educational charity (CIO no. 1155828) founded in 2002 by Mildred and Ron Cookson and based at Watlington House, Reading. It preserves, catalogues, and provides public access to historical records of mills and milling, holding more than three million documents and images across 260+ collections, with the UK's most comprehensive databases of mills (12,923 entries) and milling-related people (44,595 records). Its core technology is the AtoM (Access to Memory) archival platform powering a free online catalogue (over 100,000 records), a separate library catalogue (8,114 publications), and an online shop for image and book sales.

The Trust operates a community-led, education-first go-to-market rather than a commercial sales motion: free public catalogues are the primary access channel, supported by a weekly e-newsletter, biannual Mill Memories magazine, StoryMaps exhibitions, social media, workshops, and volunteer programmes. Fee-bearing services are limited and modest: high-resolution images at £24 each, document copying at £10 plus £3 per page, photography licences at £30 per visit, workshops at £100, webinars at £35–£50, and research services from a £250 minimum.

Revenue is generated through a mix of charitable donations, Friends of the Trust memberships, gifts in wills, project grants from bodies such as the National Lottery Heritage Fund, Swire Charitable Trust, Garfield Weston Foundation, The National Archives (Archives Revealed), and the Council of Europe/EU, and small commercial streams from image licensing, books, and workshops. The organisation is governed by a Board of Trustees chaired by Dr Ron Cookson MBE, with a small paid staff supplemented by volunteers and interns, and is accredited by The National Archives under Archive Service Accreditation awarded November 2016.

Broad incumbents

• Society for the Protection of Ancient Buildings (SPAB): Founded by William Morris in 1877 to protect historic buildings, including mills. Parent organization of the SPAB Mills Section that works directly with the Mills Archive; comparable as a heritage-preservation charity but with a far wider building-focused mandate.
• National Trust: The UK's largest conservation charity, holding many historic mill sites in its portfolio. Comparable as a UK heritage preservation charity reliant on members and donations, with overlapping audiences interested in historic mill buildings.
• English Heritage: The UK charity that manages hundreds of historic sites and monuments, including mills. Comparable as a major heritage charity with overlapping public-engagement and education programmes, though focused on physical sites rather than documentary archives.
• The National Archives (UK): The UK government's national archive and accreditation body for archive services. Awards the Archive Service Accreditation held by the Mills Archive since 2016 and funds major cataloguing work via Archives Revealed; comparable as a standards-setting archive but vastly larger and broader in scope.
• British Library: The UK's national reference library, holding a much larger and broader collection of books, journals and manuscripts. Comparable as a publicly accessible library/archive institution serving researchers, but operates at national scale across all subjects rather than milling specifically.

Direct peers

• Norfolk Windmills Trust: A regional UK trust dedicated to the preservation and study of Norfolk's windmills and watermills. Comparable as a specialist mill-heritage organization with collections, volunteers and a researcher base, though geographically limited to Norfolk.
• SPAB Mills Section: The mills-focused section of the Society for the Protection of Ancient Buildings. Source of the Foundation Collections at the Mills Archive and holds a trustee seat on the Trust's board, making it the closest peer in mission and operating model.
• Mills Research Group: A volunteer-led UK society dedicated to the study and recording of mills. Direct collaborator with the Mills Archive on the Nuts and Bolters milling terminology project, serving a similar community of mill researchers, owners and enthusiasts.

Others

• Heritage Lottery Fund (National Lottery Heritage Fund): The principal UK funder of heritage projects. Has funded the Mills Archive's Reading EmPOWERed, Nuts and Bolters and Heritage Lottery Fund-supported projects; comparable as a heritage sector participant but as a grant-maker rather than an operating archive.
• University of Reading Special Collections: University archive and rare books service that hosts the Mills Archive's undergraduate research placements and student exhibition collaborations via the UROP programme. Comparable as an academic archive partner with similar cataloguing and digitization workflows.
