BSI was first established in 1979 by Carl and Linda Tupper. The original business was selling used paperbacks; thus, "BSI" stands for Book Swap, Incorporated. Soon after opening, comics were outselling paperbacks and BSI Comics was born.

Jason and Sheila acquired BSI Comics in the aftermath of Hurricane Katrina. Jason is a corporate ex pat who now works full-time at the shop.

Carl Tupper occassionally can still be found helping out at the shop.
