The OTRR Certified Library on the Internet Archive

Who Created It: he Internet Archive, hosting the specialized preservation databases compiled by the Old Time Radio Researchers (OTRR) Group

 

What It Is: A massive, free-access digital repository of audio recordings, featuring organized, systematic metadata sheets for circulating audio collections.

 

When It Covers: The complete operational timeline of sound broadcasting (1920s through the modern era).

 

Where It Is Hosted: Online at the Internet Archive.

 

Why It Provides Provenance: This is where radio logs meet actual audio. The OTRR "Certified Sets" provide metadata logs detailing the exact lineage of an audio file—distinguishing between pristine network line recordings, military transcription discs, or off-the-air home recordings.

 

Expectation Guide: Due to its vast size, navigating the Internet Archive requires highly specific search terms (e.g., searching for "OTRR Certified"). Treat this as your primary destination for downloading the actual audio verified by the print logs.
