Hmm, yes, good point. That's stripped-down, bastardised markup aimed at a novelist who'd never seen proofreading symbols before. I gave him a crib sheet with a guide to basic markup along with the first instalment, but ended up developing a sort of hybrid of official symbols and written notes as we went along. The fact that full stops were circled but commas and other punctuation weren't just confused him. Probably not the best page to have used in the design, now that you mention it.

But I think I would indeed spot the sort of things you're talking about in the OUP stuff. I could send you a three-page sample I recently did for someone else (it's a Word doc with Track Changes, plus a separate document summarising the document-wide changes and decisions I made) if you like?
