Joe Massey and Emily Lloyd pointed my attention to C. A. Conrad's Neglectorino Project, a place where poets can note their favorite "less commonly read" poets.
My addition to the list? James White and his The Salt Ecstasies. I read recently that Mark Doty would be rereleasing this book through a new Graywolf Press series. I'm glad. It's a powerful work.
I just tried googling him to add an image of him, his book—and then, anything related—but there's nothing there.
