The title should be formatted with either quotation marks or italics. Here are two correct ways to format the title:
"Witness to Apocalypse" documents a project that gathered stories from New Yorkers in an effort to record what happened to them in the moments and days leading up to and after the attacks on the World Trade Center in September 2001.

Both of these options are widely accepted and appropriate for different contexts. Using quotation marks is more common in journalism and in shorter pieces of writing, while using italics is more common in academic writing or in longer pieces of writing like books or articles. Bold and underlined are also sometimes used to format titles, but this practice has become less common in recent years.
