Accessibility

You can use the site’s links and form controls with a keyboard. You can enlarge text with browser zoom. You can read page content without using the maps. Images that carry information have text alternatives or captions. Historical handwriting and scanned documents can be hard to read, so where a transcription exists, we link to it beside the item. Our linked reading resources include text and audio options.

Some parts of the site, and some services we link to, are not yet fully accessible.

Not every handwritten letter or scanned document has a transcription.

Third-party services such as external catalogues, booking sites, PDFs, maps and spam checks may work differently from this website. Their providers are responsible for them.

If the contact form or its security check prevents you from contacting us, use the contact details on our press and media page.

We aim to meet WCAG 2.2 Level AA. We have not completed an independent audit, and we do not claim certified compliance. We are continuing to check keyboard navigation, contrast, zoom, alternative text and forms as the website develops.

In-house code checks, automated checks and browser spot checks were carried out on 27–29 October 2026. A full accessibility audit, including comprehensive phone testing, remains outstanding.

If something on the site does not work for you, please tell us. Contact us about accessibility. Tell us the page address, what stopped you and the format or help you need. You do not need to tell us about a diagnosis.
