I sold iDIDJ Australia's 2nd last copy of the 1937 edition of
A Black Civilization today to the
AIATSIS Library in Canberra, ACT. For scholars and researchers, the AIATSIS Library is an invaluable resource with "... the most comprehensive collection of print materials on Australian Indigenous studies in the world" (AIATSIS Library website). Check it out if you're ever in Canberra, or browse their online catalogue for literature you might not find in any other library anywhere in the world.
Anyway, I have one copy left of this coveted 1937 first edition if there are any Yolngu-philes out there looking for this rare publication... it isn't available anywhere else as far as I know. Take a look at the iDIDJ Store's book section, reference bLW37:
