Two sets of modern Japanese literature reference books. There are no writings or markings. I apologize if I missed anything. There are eraser marks on the "New Techniques for Solving Modern Japanese Literature" book. The covers have some scratches and yellowing, but there are no problems with reading. I am selling these because I no longer need them. Please purchase only if you understand that these have been stored at home.
