Sounds interesting. I gotta get on this, because sometimes I neglect to work up a list and before I know it, I miss out on the year's Classic Comics Christmas.
Questions: Are less frequently published titles like quarterlies and annuals eligible? Some quarterlies seem like they be within the spirit of the rules. On the other, it seems like a series of annuals are within the letter of law as currently drafted, but may or may not be within the spirit of the law. There's a gap of a year or more between issues, and there an adjunct of sorts to a monthly series that goes far beyond 12 issues. And Giant-Size Such-and-Such seems to fall in between those categories.
