Singularities by Susan Howe.
I read this in grad school and wrote all over it, mostly on the fly-leaf, some underlining, and very obnoxiously I wrote one poem all over page 27. If you're still cool with that, I think $2 will ship this one. If you want a pristine copy, try here.
Howe is mostly concerned with recovering historical voices, layering and mixing language, sometimes literally on the page by disobeying typical typography. An archeology of New England in poetry.
I'll admit I don't really get it. This book is challenging, using archaic spelling and breaking narratives to achieve the feel of little recovered pieces, marginalia and potsherds.
