An online digital history organization made more than 10,000 photos of Chattanooga from the 1960s available on Flickr this weekend.

Picnooga released the photos, which are from the Chattanooga News-Free Press collection via the Chattanooga History Center.

The photos are from January 1961 through January 1966 and are displayed in reverse chronological order on the site. There are some gaps in coverage because half the collection remains at The Public Library awaiting scanning.

According to Picnooga founder David Moon, the total collection contains about 29,000 photos from the 1940s, ’50s and ’60s. Picnooga will release the entire collection-a decade at a time-over the next few months.

“Flickr was the most efficient way to publish the archive,” Moon said in a Facebook post. “You can zoom on faces, comment and save to favorites.”

Many of the photos are not tagged, but Moon hopes the general public will spend time helping identify some of the faces and locations. He encourages followers to sign up for a Flickr account to help tag the photos.

Moon said the collection is as if Facebook existed in the 1960s.

“The photos are just a slice of everyday life and happenings,” he said. “Newspapers once filled that need for a granular level of social news, individuals, and community happenings and achievements.”

Recently, photos from the Picnooga-Chattanooga History Center partnership were featured on Mashable. The photos depict the Chattanooga sit-ins of 1960. The first took place Feb. 19, 1960, at McClellan’s segregated lunch counter on North Market Street. Click here to view the photos.
