perhaps publish some sample recipes from your books?
or
maybe make some youtube videos of you cooking your receipes, tell them about your book, have some links to your book.

GOOD LUCK!

i agree you should link your books to the post also so we can check them out

Well good luck to you with your books. I think the best way is to tell people, because if the cook books are good, they will get noticed!

Post them on here! Are they FREE or a very low price? The cheaper they are the better the chance of being clicked on and looked at.
