The code for generating the tables is shown below:
create table book ( bookid char(12) not null, dimensions char(15), availability char(30), booktype char(20), publisher char(20), isbn char(20), itemsinstock int(3), price float(5,2), title char(50), toc char(24), picture char(36), primary key (bookid));
create table author ( authorid char(12) not null, name char(24), primary key (authorid));
create table authorbook ( bookid char(12) not null references book, authorid char(12) not null references author, primary key(bookid,authorid));
Basically, I want to get it in the format specified in the message, i.e. if the title is the same, I do not want it to be printed again...
Any ideas?

It would help a lot to get answers if you shared the description of all three tables.
