How do you remove books that are nolonger published from your profile? > Likes and Comments

I have three questions. Somebody please help

Question 1.
-How do you remove books that are nolonger published on Amazon from your account profile?

Question 2.
-How do I ungroup books that were previously grouped so that reviews of one book don't show up on another different title?

3. Question 3.
-How do you add books to your profile? Let's say the books already exist on Goodreads library but not visible to readers who visit your account profile. How do you make the link?
