The workshops, meetings, gardens and neighbourhoods pictured on Common Inquiry are all public-domain or CC0 images. Wikimedia Commons supplied most of them, and several are US federal government works, public domain in the United States. We only cropped them to 3:2, resized them and converted them to WebP.

The residents, researchers and places in these images illustrate a theme; none of them is connected with Common Inquiry or endorses it. Pictures from government or organisational events are illustrations only, and the journal has no tie to the agencies or groups that held them. Nothing from the former People's Knowledge network, logo or other material, is used.
