Given this comment. I am wondering if anyone is interested to buy a 2nd hand
copy of Schodde and Mason's Directory. I am quite willing to sell mine. It
is in perfect condition, autographed (by Schodde).

Hi Graeme et al.
A quick update on the availability of Schodde and Mason's Directory - like
many CSIRO publications it is available in eBook form from:
http://www.ebooks.com/616516/directory-of-australian-birds-passerines/schodd
e-r-mason-ij/
At $195 it might be considered a tad steep though!
Cheers,
Stewart
