Taylor Swift's Eras Tour book hits stores Friday. Here's what to know.

Taylor Swift's latest release isn't a new song or album — it's a book hitting store shelves on Black Friday that commemorates the pop star's record-setting "Eras Tour." 

The volume chronicles Swift's wildly successful series of concerts, which concludes in December and which last year became the first music tour to gross over $1 billion. 

A movie version of the concert she performed on her Eras Tour also shattered box office records. It earned an estimated $96 million domestically over its opening weekend, making it the most successful concert film of all time, according to Comscore.
