Did Shakespeare Write A Lover's Complaint?

Slate looks into the mysterious authorship of a Shakespearean poem.

From the story:

I'm speaking of the decision by the Royal Shakespeare Company's publishing wing, in its recent edition of the Complete Works of Shakespeare, to subtract, delete, erase one long-standing four-century-old fixture of the Shakespearean canon: a 329-line poem called "A Lover's Complaint."

And its decision to attribute to Shakespeare a relatively recent discovery, an 18-line dedicatory poem called "To the Queen."

These changes are no small matter: Casting a poem as long as the "Complaint" out of the canon means redefining the artistic identity of our greatest poet and dramatist in a small, subtle but significant way.
