Why Wasn’t I Told?

I had never seen or heard of the Cambridge Translations from Greek Drama series until I picked up Ajax and Philoctetes at the Green Valley Book Fair on Saturday. They look quite useful for monoglot students of tragedy, and not entirely useless for scholars and teachers. I’m wondering how I managed to miss a whole series of books whose first title (of ten) came out ten years ago. Does Focus completely dominate this particular segment of the market for translated tragedies? I should probably mention that the Book Fair only had one copy of each, so no one will waste time looking for them there.
