Are you looking for images of life in World War II-era America? Need to show what Puerto Rico looked like 60 years ago? Last month the Library of Congress mounted over 3,000 images from the first half of the 20th century onto Flickr, the popular photo-sharing site.
Browsing the collection is as easy as going to LC’s main Flickr page and clicking away. Use the box at the top of the screen to search the photos by keyword. Each photo’s page also includes a link to the Library of Congress’ catalog, where you can download an uncompressed, high-resolution version.
LC may add more of their collections to Flickr, including Civil War photos. You don’t actually have to wait for that to happen, though. LC already hosts a much larger number of photos on their own site; search their catalog or browse their American Memory collection to get an idea of what’s available.
If you have another site that you’ve found useful in teaching or your work as a student, please let us know in the comments!
