That the Library of Congress has a Flickr page.
From their Flickr profile page?:
Yes. We really are THE Library of Congress.
We invite your tags and comments! Identifying information is also appreciated–many of our old photos came to us with very little description.
What is the Library of Congress?
We serve as the national library for the United States, based in Washington, DC. With more than 134 million items preserved on some 530 miles of bookshelves, we’re also the world’s largest library.
In addition to books, we have photos, maps, databases, movies, sound recordings, sheet music, manuscripts, and information in many other formats. Millions of items are online, and the full array of collections is available in DC, right across from the U.S. Capitol building
What are photographs doing in a library?
We’ve been acquiring photos since the mid-1800s when photography was the hot new technology. Because images represent life and the world so vividly, people have long enjoyed exploring our visual collections. Looking at pictures opens new windows to understanding both the past and the present. Favorite photos are often incorporated in books, TV shows, homework assignments, scholarly articles, family histories, and much more.
The Prints & Photographs Division takes care of 14 million of the Library’s pictures and features more than 1 million through online catalogs. Offering historical photo collections through Flickr is a welcome opportunity to share some of our most popular images more widely.
I was wasn’t aware they had their own blog.
Their Flickr page only has two sets of pics, but this one caught my attention.
