I think, within the guidelines we should strongly stick to the “Book” / “Edition” distinction.
New users might get confused with the Book = entity / book = everyday word differentiation.
I see that the rules for the “English Title” now differ from what was discussed before
“English Title” on ‘books’ - General - ctlgs
I don’t get why we don’t stick to the ‘direct translation of the original language title’. By the current rule, I would have to search if there is a translated edition already. And the ‘won’t appear in searches’ argument is kind of irrelevant, because it still wouldn’t even if it’s in the “English Title” field.
