The Wellcome Library has donated over 100,000 images on medical history, which have now been uploaded on Wikimedia Commons. The high resolution photographs and scans are used to illustrate a wide range of Wikipedia articles such as disease, art history, cartoons, sexuality and biographies.

Wellcome Images provide free public access to their digital collection online, covering topics from medical and social history to current healthcare and biomedical science. Wellcome Images is part of the Wellcome Collection, with an extensive range of manuscripts, archives, paintings, prints and drawings. See http://wellcomeimages.org.

The Wellcome Library are thrilled with the mass upload of the historical Wellcome Images to Wiki commons, and would like to thank Wikimedia UK for its support, and Fae, as an independent Wikimedia Commons volunteer, who has worked on the uploads over the past few months. We are delighted that 100k images from our extraordinarily diverse collection are now visible through the most consulted information resource on the planet.

Robert Kiley, Acting Head of Wellcome Library.

As a longtime Wikimedia Commons supporter, I contacted Wellcome Images with a proposal to upload the entire collection, which Wellcome Images supplied on a hard disk (the collection took 300 gigabytes). The images have proven highly popular, with nearly 500 fellow Wikimedia Commons volunteers helping to categorize and reuse the images in Wikipedia articles, along with significant interest for related projects with Wiki Project Med and Wikimedia LGBT+. The images were released on the Wellcome Library’s website in 2014 with a non-commercial restriction. Following discussion and a workshop with Wikimedia volunteers, they were changed over to a CC-BY license, to ensure that the public can easily reuse the collection for any purpose.
