[ SLANG ][ FANFICTION ][ NOUN ]
The full accumulated set of a single fan's headcanons treated as one organized collection, distinct from a headcanon layer by being the complete collection rather than one individual belief within it.
REAL-WORLD EXAMPLE
"Her headcanon library for that character is honestly more detailed than the actual show's backstory."
LORE & ORIGIN
Extends 'headcanon-layer' up a level, borrowing 'library' the same way collections of related items get formalized elsewhere in the dictionary.
