This product is the first half (14 volumes, volumes 1-14) of a complete set of 30 volumes. This is sold as a complete set, so please purchase both the first half and the second half of the complete 30-volume set as a set of two items. This complete set includes volumes 1 to 25, and supplementary volumes 1 to 4, for a total of 29 volumes and 30 books. Due to shipping considerations, the complete set is divided into two parts and sold in two boxes. (All volumes and books are included in the two boxes) This complete set is a rare book with a limited print run, printed in three installments: April and October of 1991, and March of 1992. Many volumes are unused, but there are age-related stains on the outer boxes and the top and front edges of the volumes themselves (multiple photos attached). The printed surfaces of the volumes, including the margins, show almost no stains within the range of volumes that have been opened. However, volume 6 has stains on the top and front edges that have discolored the margins of the printed surface. Photos of this area are also attached (p158 top edge and p38 front). Please understand that there may be other age-related changes. The total weight of the 30-volume set is approximately 40 kg, and the total width when the books are placed upright on a horizontal shelf is approximately 130 centimeters. The depth of the books with covers is approximately 17 cm, and the height is approximately 23.5 cm. Two volumes are approximately 26.5 cm square and approximately 27 cm deep, and 38 cm high. Please refer to the attached photos.
