The B'omarr Registry was a bound manuscript which kept record of the members of the B'omarr Order who achieved enlightenment. In addition to this, the thick registry contained a record of some of the monks' greatest philosophical musings. A copy of the Registry was known to be held in Shiin's Library in Mos Eisley.
