The list of prohibited books was called the Index.

I am assuming that you are asking for a list of prohibited books issued by the Catholic Church, not on. Further, it's just Catholic, not Roman Catholic. Roman is an epithet first commonly used in England after the protestant revolt to describe the Catholic Church. It is never used by the official Catholic Church. The last Index of Prohibited Books was issued in 1948 and the entire Index was abolished by Pope Paul VI in 1966. You may see the 1948 Index at the link below.

Joseph Maria Pernicone has written:

'The ecclesiastical prohibition of books' -- subject(s): Catholic Church, Index librorum prohibitorum, Prohibited books (Canon law)

No. Mostly only non-fiction (real/information) books have an index. Novels and picture books do not.
