(2 May 2019) A new CC Search front end debuts this week. Developed by Creative Commons and a community of volunteer developers, the tool allows users to find and use some 300 million images from openly licensed and public domain works.
The search function provides a single place to look for images from 19 collections, including Flickr (which is currently the source for the bulk of the content — some 289 million pictures), Bēhance, Geograph Britain and Ireland and DeviantArt.
