Help us to describe our records online

We are encouraging users to help tag and contribute to our records, both in our online catalogue, Discovery, and on other interfaces such as the photo-sharing website Flickr. You do not need to contact us to take part in these activities.

Operation War Diary

Take part in Operation War Diary, our innovative crowdsourcing project, by reading recently digitised First World War diaries and tagging key pieces of information on each page.

A ten-minute tutorial gives a step by step guide of what to look for, including people and activites described in the diaries, and instructions on how to tag this data. The volunteer Citizen Historians involved in this project will unlock this important information, enabling family historians and academic researchers to search the diaries by name and place. This project is being run in conjunction with the Imperial War Museums (IWM) and crowd-sourcing experts Zooniverse.


The introduction of a tagging tool to Discovery allows users to assign key words or phrases to our records, helping other users to find records that they previously wouldn't have known about. As much of the catalogue data also uses older language to describe our records, tagging presents the opportunity to refresh and modernise some of this language, making it relevant to today's users.

This will lay the foundations for future developments, such as adding user-generated content to catalogue descriptions and tagging records with location information.

Through a lens

Our 'Through a lens' series has seen the publication on Flickr of the CO 1069 series of photographs, providing online access to thousands of photographs previously only available at Kew. This has given users the opportunity to engage with our records, to tag and contribute comments and suggestions to help improve catalogue descriptions and geographical references. Our ultimate intention is to extract these contributions from Flickr and add them to our catalogue.

Building on the success of our Africa through a lens project in 2011, and the Your Caribbean Heritage cataloguing project, our wider Caribbean through a lens project seeks to build relationships with under-represented communities regionally and engage with non-traditional audiences of archives.
