ETH-Bibliothek's photographic and audio-visual documents are curated by the Image Archive. Its collection of more than 3 million visual sources include ETH Zurich's Portrait and View Collection, images included in various personal papers and major image collections, among them pictures by the photographic agency Comet Photo AG, aerial photographs of the Luftbild Schweiz Archive or the Swissair Photo Archive. Initiated by a partnership project with Wikimedia CH, public-domain and CC BY-SA-licensed content in the Image Archive are being uploaded to Wikimedia Commons since 2016.
