Every register we consult, its licence, and the attribution it asks for.

Wikidata: Data from Wikidata, dedicated to the public domain under CC0.
Wikipedia: Article text and titles under CC BY-SA 4.0. Each article we cite is linked from the page that uses it. Prose we derive from Wikipedia is shared under the same licence.
Wikimedia Commons: Each photograph carries its own licence, most often CC BY-SA. The author, licence and file page are shown with every photograph, in the gallery and the lightbox. We never alter photographs on the page.
Open Plaques: Open Plaques asks that its site is not crawled, so we do not fetch from it. Plaques come from Wikidata, and link to their Open Plaques page where Wikidata records one.
Share cards: The image shown when a page is shared crops a Commons photograph. A crop is an adaptation, so each card carries the photograph's credit with the word "cropped", and the card is shared under the photograph's own licence (CC BY-SA where the photograph is CC BY-SA).
