Over the years, we’ve discovered that social media is a pretty awesome way to learn more about our collections. Recently, a Twitter conversation helped us unravel the true identity of an incredible natural history artist. In November, one of our star citizen scientists Siobhan Leachman was working on adding artist machine tags to images in the BHL Flickr (want to learn more about how to do that? See this guide!). She was working on Wonders of the Bird World (1921), which was digitized for BHL by Cornell University Library. The title page stated that it was illustrated by A.T. Elwes.
