Italics required?

[PlacidRan]

Are the titles of fairy tales italicized or are they placed inside the quotation marks?

I assume you mean within a sentence, such as 'I read Cinderella to my daughter every night'.

I would recommend using italics if possible. If not, use quotation marks.

(And not only fairy tales: any title.)

Thank you.

I generally use italics too, but what's the context? Certain types of writing may require specific formatting.
