A Literary History of the American West

My copy clocks in at a whopping 1,353 pages.

This massive book sponsored by The Western Literature Association contains dozens of essays by noted Western literary scholars on aspects of the Western
written canon both familiar and obscure [to this reader, at least.]

Do you want information on the phenomena of Mid-Western "Farm" literature? It's here.

Details on Scandinavian Immigrant Literature? Bingo!

A careful examination of Frank Dobie? Yep.

Admittedly, this is a scholarly work and may hold less appeal for the strictly formula Western reader, but I'd say any true lover of the genre will find ready fodder for future consumption within.
