The collection of sound recordings of 44 audiocassette tapes and 1 mini-disc document the actual, unedited day-to-day radio broadcast of Radio Veritas, (a Catholic–owned radio station at the outskirts of Manila), DZRJ/DZRB, Radio Bandido, (a privately-owned radio station in Quezon City, then under the Ministry of National Defense), DZRH (a privately-owned radio station in Manila) and Voice of the Philippines (a government-owned radio station taken over by the people led by Radio Veritas on the 24th of February, 1986). The unbroken radio record over four days in 1986 is an unvarnished chronicle of a nation and its people at a crucial time in its history.

The collection was inscribed in UNESCO’s Memory of the World programme in 2003.
