I promise I really will get up to date in the next few days!
There are a bunch more obscenity-filled ones to finish off Book 3, then I'll take a break from the numerical sequence of books and do the de spectaculis before continuing with Book 4. The plan then will be to get to Book 6, put in the Xenia (="Book 13"), continue to Book 9, then do the Apophoreta (="Book 14") before finishing off up to Book 12.
The three Books I'm interpolating into the order are in fact M's first (even though 13 and 14 are numbered as though they came after the others!). Splitting them up like this should hopefully break things up a bit, and also ensure that we actually end with M's last published poems.
