The Essentials in Literature Textbooks are not anthologies. Each level includes a mixture of American, British, and World Literature. Categories of each work are indicated in the Teacher Handbooks (7-9) or Resource Books (10-12) of each level.
They are also included in the "Literature Assets" page on our website. (https://essentialsinwriting.com/homeschool-resource/literature/essentials-in-literature-asset-links/) Students who work through Essentials in Literature Levels 9, 10, 11, and 12 will be exposed to the equivalent of American, British, and World Literature courses.
