If you are referring to social etiquette, such as never presenting a lady to a gentleman (except in rare circumstances) or saying "How do you do?" instead of "Pleased to meet you" when introduced, then there are hundreds of sources. Two common ones are Emily Post and Amy Vanderbilt. Emily Post's 1922 edition can be found online here.
Incidentally, Emily Post alludes several times to the shallowness of manners without real moral character. The actions (manners) generally give form to purity of heart.
