"Bibliografia Degli Studi Su Rousseau (1941-1990)" is a massive 1385 page, 7"x9.5" hardcover compiled by Giuseppe A. Roggerone and Pia I. Vergine, and published in 1992 in Italy by Milella. All text is in Italian. It's a bibliography of books and articles written about the 18th century French philosopher Jean-Jacques Rousseau - most entries include a brief synopsis. 

The book is in acceptable condition, being ex-library with the usual markings and attachments. There's no dust jacket. The cloth cover has a spot of wear on the front where the authors are listed, bumped corners and spine top, a few spots and smudges. There's paper loss on the spine where a library sticker was removed. Library marks are confined to the covers, page edges and ffep - the interior is otherwise unmarked, and the binding is firm.
