Maybe I've missed the boat, but I didn't find "heaps" of books at Andamooka. Sure, there are a number of programming entries, mostly for KDE and Linux.

And I was disappointed with Computer Literatur for it's out of date (Perl 4) version of the Perl Man Page, broken links, and a dysfunctional English translation (along the lines of "Yes, Virginia, there's an English version. But it's just a stub, and the links are broken. But we have the Union Jack graphic up and running!") However, there seems to be a lot there, so perhaps a number of gems in the haystack.

But they're free, and I like the price of admission.
