Robert Yarnall Richie (1908-1984) worked as a free-lance commercial and industrial photographer for many large corporations including those in the automobile, aviation, chemical, mining, petroleum, railroad, shipping, steel and other industries, both in the U.S. and overseas. The collection, held by Southern Methodist University's DeGolyer Library, contains corporate and industrial photographs made by Richie from 1932-1975. Southern Methodist University's Central University Libraries (CUL) Digital Collections includes the digital libraries and online digital collections from the six Central University Libraries. Our ongoing projects include the creation of digital collections of Mexican photographs, locomotives, Texas history, art, and currency notes, and more.

A very large dataset of various big guns, howitzers, mortars, columbiads, all types of canon-like things - everything besides machine guns and rockets. This collection as well as all massive collections on Picryl.com required two steps: First, we picked a set to train AI vision to recognize cannon artillery, and after that, ran all 25M+ images in our database through our image recognition network. All media in the collection is in the public domain. There is no limitation on the dataset usage - educational, scientific, or commercial.
