Because the information and images you can see in Lives of the First World War come from a variety of sources, many different conditions apply. This means you will need to check each one to see if or how it can be reused.
You can reuse facts you see on the platform for non-commercial purposes. If you want to re-use an image, it will depend on who owns the rights and what the terms are. Some images whose rights are owned by IWM will be available for non-commercial reuse.
