What exactly do you mean by "no access with K"? I'd like to point out this problem, regardless: when you "learn" the skill, make sure you are actually selecting the character you want to learn the skill. It doesn't matter whose inventory the skill book is in; it is the character you're selecting that will learn it. You don't have to give the skill book to the character, but you have to select them when you learn the skill.
For example, in my case, this one time Lohse was having a bunch of Warfare books, I wanted the Red Prince to learn them, but didn't notice I was selecting Sebille, so Sebille ended up learning all those skills instead.
Is this by any chance what's happening in your case?
