Do you know what style guide is most common in book publishing in the UK?

@junecasagrande Hey, @unamccormack or @Scifibulletin , can you answer?

@wleisner @unamccormack @Scifibulletin Thanks, William. I googled and I *think* I got the answer. Looks like The Oxford Manual of Style? Hard to tell if that's the reigning authority or if there are others, though.
