Hey, thanks for responding and not leaving me all by myself here!
The second question's answer is that one question mark serves as two.
Hope answers that.
The first one, well, my expert at Charles Darling's web site was really just guessing. I have the question at the Chicago Manual of Style as well, so I hope to hear back from them.
Anyway, Mr. Darling's take is also what the copyeditor did to the manuscript, so it's probably right.
Darling would close the preceding paragraph with quotations and not have any with the extract.
I really like your solution best; that's how the Chicago Manual would handle it say, if it weren't set as an extract. Each new stanza would have a new opening quotation mark, with only one at the end. Slashes go in between the line breaks.
Which sort of begs the question, I mean, if it's all run in together in one paragraph, then, well, do you just plop in an opening quotation mark right in the middle of the paragraph???? Um . . . would that go before or after the slash?????
One of the poems in the ms is run in, well sort of, with the SLASHES, and then, by golly, the copyeditor also marked it as an EXTRACT. It appears blocked in paragraph form and centered in proofs two (?) em spaces from the edges, with one line space before and after.
I KNOW that's wrong, so I sort of feel smart today.
