Chrestomathy
Chrestomathy (/krɛsˈtɒməθi/ kres-TOM-ə-thee; from the Ancient Greek χρηστομάθεια “desire of learning” = χρηστός “useful” + μανθάνω “learn”) is a collection of choice literary passages, used especially as an aid in learning a subject.
In philology or in the study of literature, it is a type of reader which presents a sequence of example texts, selected to demonstrate the development of language or literary style. It is different from an anthology because of its didactic purpose.
