To the best of my knowledge this is ALL of the dramatized audiobooks made in the 90s by Simon & Schuster Audio for Star Trek TNG, TOS, DSN, Voyager and William Shatner novels. Many original rips by me in TRUE STEREO from cassettes and Discs. Enhanced/cleaned where needed, volume normalized to -3.2dB max peak with 2.2 max increase where needed to make each about the same volume.
