Volumes 5, 6, and 14 are first editions. Some items are in near-new condition, so older volumes may appear dirty, but there is no problem with reading them. There is some yellowing, but it does not affect readability. The spines of volumes 12 and 14 are faded. Other than that, there are some minor yellowing, scratches, and stains, but there is basically no problem with reading them. The condition description is based on my personal assessment. Please understand that these are used items and place your order accordingly.
