Sources and illustrations
The articles draw on the sources linked in the text. Photographs and illustrations carry individual credits and reuse terms, available by opening each image. The site uses resized JPEG thumbnails for photographs. Where sources disagree, the articles identify the differences.
Use of AI
AI tools assist with editing, building and maintaining the site, and making some illustrations. We use them to support this work and aim to distinguish illustrations from documentary photographs. We do not intend to mislead readers or pass off a generated illustration as a record of a real person, place or event.
