In col B I have some entries many of which have the word 'book' in some form
-- eg. notebook or bookmark.

In col C I have some numeric codes -- 1, 2, 3 etc.

If a cell in Col B contains the word 'book' I would like in Col D to show
what is in Col C; if the cell in Col B does not contain the word 'book', I
would like to put a 0 (zero) in Col D.

Thanks for your help!
