The Library of Congress is working to preserve the nation’s historical broadcasts

When Wilt Chamberlain smashed an NBA record in 1962 by scoring 100 points in a single game, a radio broadcast provided the only real-time account of the Stilt’s incredible feat.

When Charles Lindbergh flew the Atlantic, Franklin D. Roosevelt addressed the nation in the Depression’s depths, Allied troops landed on Normandy beaches and Babe Ruth called his shot in the 1932 World Series, radio delivered the news.

For about a century, radio has informed and entertained Americans. The passage of the years, however, has left recordings of those historical broadcasts at risk, victims of deterioration, neglect, improper storage or just the ravages of time.

The Library of Congress for decades has worked to acquire, preserve and make those recordings accessible—efforts that in recent years have increased in scope and scale.

“We have an opportunity to sustain this material and make it available, but it’s a closing window—that’s the scary part,” said Eugene DeAnna, head of the Library’s Recorded Sound Section. “It takes action now on the part of archivists, producers and scholars to move us forward at a faster rate than we’ve up to now been able to sustain.”

Radio’s Missing Era

By the 1920s, radio was a staple of everyday life, an unprecedented blend of news and entertainment, brought to life with voices and delivered over the airwaves to American homes.

Few broadcasts, however, were captured for posterity—recording equipment was bulky, expensive and not especially good. As a consequence, recordings of broadcasts of, say, big stars or historic events from the Roaring Twenties are exceedingly rare.

When Lindbergh landed at Le Bourget airport following his historic trans-Atlantic flight in 1927, announcers broadcast the chaotic scene as thousands of spectators stormed the field to welcome him to France. All that remains of that scene today are black-and-white images—and silence. No recording of the broadcast is known to exist.

That’s a common tale: Of the 500,000 or so recorded radio broadcasts preserved in the Library’s collections, only about 50 come from the 1920s. The cultural loss is enormous—the soundtrack of an era forever missing.

“We don’t have that initial foundation of radio,” DeAnna said. “So much of the early broadcasts— radio and TV—just went into the ether. They’re gone.”

Radio, on Record

That changed in the mid-1930s. Radio networks flourished, making the recording of broadcasts economically more feasible. Theapproaching war in Europe fostereda sense that these momentous events should be documented for posterity. Technological progress helped, too: Equipment got easier to use and the addition of lacquer coating to aluminum discs improved the recordings’ sound quality.

The major radio networks—CBS, Mutual and NBC—began recording most of their daily broadcasts on lacquer discs and, after World War II, on magnetic tape.

Whether those recordings survived is another matter—and that’s where preservationists and institutions such as the Library come in.

Forty years ago, Congress mandated the preservation of broadcast recordings in its 1976 revision of copyright law, legislation that directed the Library to create the American Television and Radio Archives to “preserve a permanent record of the television and radio programs.”

The foremost challenge preservationists face is the degradation, over time, of the media on which broadcasts were recorded. Tape is vulnerable to mold, brittleness and signal loss. The lacquer coating of discs chips or peels off the aluminum base. An aluminum ban during World War II prompted networks to briefly adopt glass-based lacquer discs—an even more-fragile medium.

That problem is compounded, at many institutions, by a lack of good, climate-controlled storage that can extend the life of recordings.

The Library stores its collections of broadcasts in the underground, climate-controlled vaults of its National Audio-Visual Conservation Center campus in Culpeper, Virginia. But, DeAnna said, such storage is expensive and hard to acquire for many institutions, even larger ones.

“Getting these collections scattered around the country into proper archival storage would extend the timeline for us to get them recorded to digital,” he said.

Saving Sounds of the Past

The Library tries to acquire as many historically significant radio broadcasts as possible for preservation— its holdings include such major collections as the Mutual network, the Office of War Information, Voice of America, National Public Radio, and Armed Forces Radio and Television. The foundation of its massive holdings, however, is NBC Radio—the largest, richest, most significant collection of domestic historical radio.

For decades, technicians in the Library’s Audio Preservation Unit have transferred those recordings from their original, at-risk formats to other, more-stable media. Today, they also are converted to digital formats, archived in a digital repository. Some 30,000 radio broadcasts have been preserved in these ways.

The Library promotes preservation in other ways as well, aiding institutions in the preservation of their own collections, helping establish national preservation standards and policy, and generally raising awareness—efforts that have ramped up in recent years.

In 2012, the Library issued a national recording preservation plan—a blueprint for saving America’s recorded sound heritage. An outgrowth of that plan is the Radio

Preservation Task Force, created in 2014 by the National Recording Preservation Board—itself a congressionally mandated, Library-affiliated organization.

“When considering our radio broadcast legacy, imagine how we would treasure a comparable recorded history of the 19th century, how much our understanding of the Civil War, Lincoln, slavery and reconstruction would be enhanced,” DeAnna said. “This is the perspective future generations will have.

“It has fallen to us to secure this vast trove of fragile discs, degrading tapes and ephemeral digital recordings in sustainable digital archives before they are lost time.”

  1. Ed Walker at WAMU and his revival of old radio shows was a staple for those of us who grew up sitting in front of the radio to listen eac night. Monday’s drama, Tuesday’s comedies on to Friday and the sports shows then anticipating the Sunday Jack Benny show. Great entertainment not to mention the presentation of the news. War came home to us all during the war through radio. Thanks to The Library some preservation will occur!

  2. The AFRTS discs (1942-1948) have preserved hundreds of shows. And for decades they were pressed on LPs, a relatively stable medium. Yes, you probably have to come to Washington to hear them (??), but they have certainly been preserved. There’s a treasure trove there!

  3. oops, typo, that was meant to be 1998. Please fix! thanks.

  4. James Fulton, thanks for your comments. I’m another FULTON down here in North Carolina, who loves OTR very much. Let’s keep it in circulation.

    PS. James Fulton, drop me a note; we may be KIN.

  5. please don’t forget the old rel brodcast like elder mich and his sunday morning worship ser

  6. Library also acquired the vast library of former Washington Senator and NBC announcer Bob Wolff two years ago.

  7. I really appreciate the blog that have been written in the great manner thanks to appreciate.

    • Louisa,
      Thanks for the question, and my apologies for any confusion! The broadcast goes live at 11am EDT, as there will be some programming prior to the actual swearing in. The swearing-in for Carla Hayden is at noon and should last about an hour.

  8. thanks for sharing.

  9. I love the preservation of old recordings. I am curious if any old Telegraphone wire recordings (1900, 1910s, 1920s) have been transferred to digital. I see pictures of Telegraphones on the Internet from time to time, with wire loaded on them. There could be old telephone conversations or dictation on them that would be most utterly fascinating to hear!!!
