This is a rather old item. There is yellowing, creasing, staining, tearing, writing, and warping. The covers have been disinfected. Please refrain from purchasing if you are sensitive to these issues. Individual sales are not possible. Complete set. Volumes 1, 4, 5, 7, 8, 9, 14, 16, 17, 18, 19, 21, 24, 25, 26, 27, 28, 29, 30, 31, and 32 are first editions. I was planning to get rid of these during a decluttering, but I'm putting them up for sale. Shipping may take longer during the New Year's holiday period, so please be aware of this. Thank you for looking.
