BookFic
From Fan History Wiki
BookFic is generally considered to be fiction based on novels, novellas, and/or collections of short stories. It is frequently used to delineate Fan fiction based on the source material for popular movies, such as stories based directly on The Lord of the Rings as novelized by J.R.R. Tolkein versus Lord of the Rings as produced by director Peter Jackson. Un-cinematized sources tend not to use the classification.
