to literature majors or those who simply love literature

Hey guys! Ever heard of 'The Norton Anthology of World Literature' before? I heard lit students from the USA and other parts of the globe use it as a reference for learning. I got two volumes, C and D and I am hoping that if some of you have used this or know where I could get second hand copies,can you help me get them? I just love the books, but all I got are the volumes I mentioned above. They are selling 3 volumes per pacakage and it's be a waste if I buy those two packages while already having one of the books from each set so I am looking for alternatives. Guys, esp those who are from the USA, if you can help me please PM me. I will be willing to pay for the books no matter what volume it is besides C and D. Thanks so much ㅠㅠ Also, if you can recommend literature which you think are great, please tell me. Thanks so much!
