Skyros--THAT book [DULL] is a staple that should be on everyone's shelves. It is a little dated but I cannot describe how many times I have pulled it as a resource when needed...
It is easy to read and has a goodly amount of maps, pictures, and organizational layouts.
DULL might be considered to be "dated" ... but DULL is essentially nothing more than an ecclectic translation of the BKK i.e. the Japanese Official history. We see other works still relying heavily on this work (the more recent "Shattered Sword") so the primary source, while just as dated as DULL - many volumes cited by many books (of the BKK) were written in the late 60s early 70s - isn't much less accurate than it was when written. So, DULL, still has value, he just doesn't have the details that some of us are looking for these days.
