Yes, I'm joking as usual.

But I can't believe some of the books that come up for air at these prices.
And $14 is unbelievably low .... that's a club sandwich and coffee at Denny's.
Why Attic? It's on the early end of greek (but not early-early). Certainly earlier than Koine. Indeed much early Bible scholarship was based on Attic instead of the Holy Ghost language.
Oddly, it's keyed by english, effectively operating as a semantic domain source (eg meaning > greek word, though some call it a 'dictionary').
Should you bid? Certainly if you're into the earlier greek classics ... comparables are always good in Logos. And moving backwards in the LXX, it'd be a good comparison to the good LXX Dictionary we don't have.
By the way, I got TWO emails on the Attic. I thought initially that Logos was just overly excited!! But then I forgot I had several bids on this one (yes, joking).
