Sources for Rules
CMOS, MLA & APA
The traditional rule, as found in the Chicago Manual of Style, MLA Hand book and the Publication Manual of the American Psychological Association is a singular noun, common and proper, ending in s forms the possessive by adding 's: house/house's, boss/boss's, Davis/Davis's, Charles/Charles's. This adds an additional syllable to the original word: /ɪs/ or /ɪz/, depending upon the previous consonant. Exceptions to this rule are ancient names: Jesus', Moses', Socrates', Euripides'.
Plural nouns ending in s form the possessive by adding an apostrophe: parents' love, friends' support, the Williamses' house Joneses' car. Exceptions to the rule are plural nouns with irregular forms: children's toys, women's fashions.
AP Stylebook
A more modern approach can be found in the AP Stylebook, which specifies the guidelines for news publications:
Singular common nouns ending in s: add 's unless the next word begins with s: the hostess's invitation, the hostess' seat; the witness's answer; the witness' story.
Singular proper nouns ending in s: add an apostrophe: Williams' plays, Dickens' novels, Hercules' labors, Jesus' life (but not St. James's Palace).
Plural nouns ending in s add only an apostrophe: the girls' toys, the horses' tail, the states' rights, the boss' office.
