Biography is the record of the author of a work. Your name, date of the work and other addresses are located in the biography. Without it, we would not know that the play Hamlet was William Shakespeare, or that Pieta was the work of Michelangelo.
In short, a bibliography serves to confirm and organize your research, monitor sources, list possible topics and avoid unintentional plagiarism. So, through the bibliography, your research gains credibility and becomes accurate and praised.
My favorite is Abraham Lincoln. He is an important president as he has freed the slaves and abolished slavery forever with his emancipation proclamation. He also brought our country through the civil war which ended with a great union win.
