副詞

in one's book

1. In one's opinion.
   • (Can we date this quote?) "Queensland Australia, is bigger than Texas, and man we've got it two-third covered", Allen Brandt, Billboard magazine

     I'll qualify that in a moment, but in my book I think when it comes to sheer professionalism, there's nothing quite like an American broadcaster.

2. Used other than as an idiom: see in,‎ one's,‎ book.
