These are the handful of story books tied in to the recent Spider-Man movies for which we don't have a dedicated title. Note that most of the kids junior novel and picture/story movie tie-in books were published by HarperCollins and hence are filed under Spider-Man Books (HarperCollins).
Note also that that various movie novelizations have their own dedicated title Spider-Man Books (Movie Novelization).
If you're looking for Activity, Coloring and Sticker books related to the movie they are filed separately under a number of "coloring/activity books" titles, e.g. Spider-Man Color/Activity Books (Paradise), Spider-Man Color/Activity (Funtastic), and Spider-Man Collectable Sticker Albums.
Plus there were also two audio books released for the second film, which are filed with our Audio items under the Spider-Man Electronic Audio Books title.
