@Library Lady can you help with the ISBN's for the Supplement to the Official Records
I found the ISBN listed as follows by
the University of Pittsburgh , but I'm certainly no expert and can't verify that it is correct
ISBN : 1568372752 (set : acid-free paper)
ISBN : 1568372760 (pt.1, v.1)
And
WorldCat lists the ISBN's as follows:
9781568372754, 9781568372761, 9781568372778, 9781568372808, 9781568372938, 9781568373119, 9781568373270, 9781568372860, 9781568372877, 9781568373171, 1568372752, 1568372760, 1568372779, 1568372809, 1568372930, 1568373112, 1568373279, 1568372868, 1568372876, 1568373171
