'The Librarians' season 3: When and where to watch the finale

TNT will air the season three finale of its popular drama, The Librarians, at 8 p.m. Eastern on Sunday. The series, a spinoff of The Librarian film franchise starring Noah Wyle, follows X-Men's Rebecca Romijn as Eve Baird — the Library's choice as "Guardian" — as she opposes supernatural threats with the help of her team of Librarians. 

Of course, if you're otherwise engaged during that time — perhaps you'll be watching the AFC Championship game between the New England Patriots and Pittsburgh Steelers — you can still catch the finale afterward.

As long as you have a cable subscription, you can watch the first nine episodes of The Librarians' third season on TNT's website, with the finale set to become available Monday. You can also catch episodes of The Librarians on TNT On Demand after they air.
