Finding photographs
Every one of these is a search, not a guess: the event is documented, so the pictures exist somewhere. Start here.
- Wikimedia Commons — freely licensed images, with the licence stated on every file. This is the only source we republish from.
- The reference article — its own illustrations, and its citations to archives.
- Image search filtered to reusable licences — useful for tracing which institution holds a picture.
- National and municipal archives of United States, and the picture desks of newspapers published there at the time.
Check the licence before you reuse anything. A photograph being online, or being old, does not make it free; in most countries a 1960s press photograph is still in copyright.
