Emily Dickinson's Reading, 1836 - 1886, by Jack L. Capps
Hardcover in Dust Jacket. 
The book is in Very Good Condition; The Dust Jacket looks like it had enough of Emily's reading, needed an adventure, wriggled free and  went to pub overnight, then crawled home a little worse for wear. Missing top right corner, and faint stain over "ck" in Dickinson on cover. Other than that, dust jacket remains respectable.
