Since it's in unsorted, we can look at it. I unpacked it and found
that disk 2 is the wrong size - it's too big for a disk image (145,400
as opposed to 143,360 bytes). Booting "side 1" asks for "side 2," and
if I truncate it to 143,360 bytes, it doesn't work.
The "Giant_World_Side_B.dsk" image is pretty messed up. The beginning
of it is definitely not a disk image, and the last few "tracks" are
actually a nibble image, not bytes. In between, there is clearly some
recognizable data, but there's also a "giantb.dsk"--which almost
certainly is unrelated to the original disk image.
Looks like a do-over is called for.

I'll take a look at it.
They do run extremely well (if no transmission corruptions) with the
AppleWin emulator.
giantb.dsk is the name the dsk usually has. I gave it the longer name
so it would not get lost in all of asimov's listings, but, by
alphabetical order, stay with the documentation, etc.
It is possible this was a disk image generated with the 2inaPC
emulator's data transfer program -- that always added a prologue (I -
think- it was a prologue) that increased the DSK's size.
