The State Library of New South Wales' major subject strengths are Australian history, culture and literature, including Aboriginal studies, Antarctic exploration, family history and genealogy, business and management, social sciences, applied science, biography, health and law. The State Library is home to one of Australia’s most significant historical and heritage collections. As well as nearly 11 kilometres of manuscripts – from nine 1788 First Fleet journals through to the archives of contemporary organisations and writers – the Library holds more than one million photographs. From the earliest surviving photograph taken in Australia – in January 1845 – through to digital photographs taken last month, the Library’s unrivalled photographic collections document with powerful clarity the way Australians have lived their lives over two centuries. You can find out more about the State Library's photographic collections on our website: www.sl.nsw.gov.au/about/collections/photographs.html More broadly the Library’s collecting reach spans a multitude of platforms: the Library’s mission is to collect, preserve and make accessible the documentary heritage of New South Wales. It holds over 5 million items including books, oil paintings, watercolours, architectural plans, engravings & lithographs, magazines and periodicals, posters, ephemera, sheet music, talking books, maps, CD-ROMs, newspapers, microfilm and microfiche, films and videos, computer software, kits, sound recordings, photographs, coins, postage stamps and other objects.

This collection as well as all massive collections on Picryl.com required two steps: First, we picked a manually curated set to train AI vision to recognize windmills, and after that, we run image recognition through all 25M+ images in our database. All media in the collection is in the public domain. There is no limitation on the dataset usage - educational, scientific, or commercial.
