In the Muse can’t believe it’s been a year since the Music Division joined the Library of Congress’s efforts on Flickr Commons. On July 30, 2010, we uploaded the first batch of photos from the William P. Gottlieb Collection to the popular photo sharing site. And it is a happy coincidence that we belatedly celebrate this milestone on the eve of Louis Armstrong’s birthday. Browse this vast collection, and listen to some Louis tonight.
