A question on autobiographical poetry

It seems I have developed a reputation as an autobiographer and theorist of autobiography, whatever that means.

As a consequence, an academic has asked me a question to which I do not know the answer. Perhaps you out there, my fellow bloggers and poets, will know more than me and I can pass on the information to the good person who is conducting research on the issue.

She asks the question:
What’s the best introduction to autobiographical poetry?

Again does such a thing exist? I can only think of poets who write autobiographically and that pretty well covers all of you, but maybe some are more obvious about it.
