Flickr Commons Collections

The U.S National Library of Medicine's History of Medicine Division collects, preserves, and makes available one of the world’s richest collections of historical material related to human health and disease. The holdings include pre-1914 books, pre-1871 journals, archives and modern manuscripts, historical prints, photographs and films. The first seven health related albums which include book illustrations, posters, prints, trade cards and photographs have currently been uploaded to the Commons : https://www.flickr.com/photos/nlmhmd/

The Internet Archive has uploaded more than 14 million public domain images to Flickr  spanning a huge wealth of topics. Each image includes detailed descriptions, including the subject tags of the book it came from and the text immediately surrounding it on the page: https://www.flickr.com/photos/internetarchivebookimages/
One of the purposes of the Internet Archive is to offer permanent access to historical collections that exist in digital format, including texts, audio, moving images, and archived web pages.

The key goal of Flickr Commons is to share material from the world's public photography archives.
