Yale University announced that they are making their 250,000 digital image library freely available on the web.
See this slideshow that showcases some of the images that were released to the public. According to Cory Doctorow’s post and comments, “high resolution” might be exaggerated (most images are 700 pixels in width, making them unsuitable for print), but still, this collection is impressive.
These images all have different copyright licenses, using most of them require you to contact one of Yale’s division (Library, Art Collections, etc.). Institutionally, the creation and dissemination of digital content is a priority, as explained on the Office of Digital Assets and Infrastructure website, is considered a strategic priority for Yale.
