In an essay do you italicize the name of the book? what do you do to the author's name and quotes? what is the difference between house's and houses'?

Thank You Very Much
Hi Angie,

Yes, italicize book titles, or underline them if you are handwriting.

I'm not sure what you want to do with the author's name-- no special treatment; similarly with quotes-- putting them in quotation marks (" ") is all you need do.

House's is the singular possessive: 'My house's roof is leaky'
Houses' is the plural possessive: 'The neighborhood's houses' roofs are leaky'

However, we don't often use this form for inanimate objects, preferring the 'of' form: 'The roofs of the neighbors' houses are leaky.'
Thank You Mister Micawber
