Guidebook: Soundrary

This mini-supplement briefly details what a public soundrary is and notes a few notable technicians who knew how to use the sound collecting crystals and playback their voices. This supplement also describes 3 notable crystals. Illustrations inside are done in watercolor.  This PDF is v0.1 and was paid for and made for my Patrons over on Patreon (https://www.patreon.com/thomasnovosel).
