I already explained to you why it's unimportant and you are about 20 years late in your comments. First and foremost based upon photos you posted of yourself it's likely you never experienced the days before electronic word processing and digital photography so you have no concept of the enormity of the task to produce the 15 Volume encyclopedia. Next, those who are familiar with the encyclopedia have long been aware of dozens if not hundreds of inconsistencies and errors, but it's "News to you." There are processes in place to deal with those issues. When General Choi was alive it was simpler. You could simply ask if it was an error he would simply say "Book Wrong". Sometimes this was followed by Technical correction bulletins and / or revisions in later editions. Sometimes that never happened.
