This BBC report (link) suggests that we should use "Dickens' Great Expectations", but I remember there is a rule from Strunk and White (here) that would suggest "Dickens's Great Expectations".

    If you really want to be confused consider the spelling and pronunciation of The Court of Saint James's, a double layer possessive with the possessive s of the second layer possessive pronounced in contravention of the 'rule' that possessive esses attached to words ending in s are silent.
