The sacred texts of such and such
Forbidden texts full of magical spells that can disrupt the laws of physics play an integral role in the movie. In the comics, one book in particularly tied to Doctor Strange’s story: the Book of the Vishanti. Written in Babylon several millennia ago, Vishanti is the most powerful text of white magic on Earth and a great source of Strange's power. Its seemingly endless pages hold not only spells but important mystical history. It's such a coveted possession that the evil sorcerer Kaluu stole it, memorized it, and then sent it to the distant past. Which leads the Ancient One and Doctor Strange on a time-traveling adventure in Strange Tales #150. Strange even uses the book to deflect magic in this issue, which leads Kaluu to hilariously scream, "Aaaarh! My own spell is being hurled back at me." Silver Age comics weren't exactly known for their subtlety.
Strange's hip NYC apartment is also magical
In the movie, three "Sanctums," stationed in New York City, London, and Hong Kong, connect to the Anicent One's main hub and act as major points of magical power, protecting the Earth from the Dark Dimension and any other threat. In the comics, there's only one, dubbed the "Sanctum Santorum," which is in Greenwich Village because New York City is the only place that really matters in the Marvel Universe. In the comics, the Sanctum has operated as the home base for the New Avengers and Defenders, both superhero groups Doctor Strange has been a part of in the past. Considering just how powerful he is and how the Eye of Agamotto is an Infinity Stone in the film, you can definitely count on him becoming an important ally for the Avengers in the future.
