(Inspired by some discussion over at the The New Lifetime Reading Plan topic)

Which authors or texts do you feel deserve a place in the literary canon, but don't currently have one?

There is, of course, not one singular, well-defined "canon" -- so interpret "the canon" as "the classics" or "required reading" or "most important works of literature" or however else you care to define it.

In particular, consider areas that the canon tends to overlook: female authors, eastern perspectives, plays (besides Shakespeare's works), etc.
