More personal organization stuff I'm sharing. I've gathered (what I think) are all of the sourcebooks released since the FanPro days and categorized them by their official era. Some items like old RPG sourcebooks (CBT Companion) and books full of outdated rules (Combat Operations) have been omitted.
