Furthermore, I had a non-school research question today that I couldn't find the answer to, so I'm leaving it out here in the hopes that D! finds it and can answer it for me using his relatively exhaustive knowledge of the publishing industry:
I purchased a couple of comics yesterday, and the month listed on them was April 2005. But it's only February 2005. Why does that happen? I've noticed it since I was about 14 or so, but I've never really wanted to know the answer until now.
