I’m so glad Geoffrey Pullum has focused on the terrible habit US publishers have with comma and period placement. There are many adjustments I’ve happily made in moving from UK conventions to US ones, but I’ve been trying to hold the line on keeping periods and commas out of quotes when they don’t belong in them.
UK publishers often put commas inside the quotation marks, in the way Pullum hates, until about 1940. It looks odd now.
Kept centre, labour and programme, too, have you?
