My current problem has to do with the rule for placing punctuation inside of or outside of quotation marks. My coworkers and I can agree that when ending a sentence with a direct quotation, or if a direct quotation contains certain punctuation, then the punctuation should be inside of the quotation marks. However, we can't get a grip on the rule for commas and non-direct-quote quotations. We are trying to adhere to the Chicago Manual of Style, but Section 6.8, where the index says the rule about quotation marks and commas is supposed to be, is instead about em and en dashes. Google searches are not being helpful either. The general consensus is that the answer is not an easy one, but I thought I'd ask anyway.
Thank you in advance.
