"In celebration of Wikipedia’s 20th anniversary on January 15th, Boston Public Library has uploaded more than 8,000 historical photographs from its archival collections to Wikimedia Commons. These images include some of the library’s most important photographic collections, and contribute to the single largest batch of uploads ever contributed to Wikimedia Commons. By uploading these public domain images, BPL is making them available so that they can be freely used to enhance Wikipedia articles, re-printed in publications, or incorporated in student projects and papers. ..."
