What is a classic? The answer to this question could vary greatly upon who you ask or what list you consult. For sure, we are not the first to ask it.
In 1850 Charles Augustin Sainte-Beuve (1804–1869) stated his answer to the question “What is a Classic?”:
“The idea of a classic implies something that has continuance and consistence, and which produces unity and tradition, fashions and transmits itself, and endures….
In 1920, Fannie M. Clark, a teacher at the Rozelle School in East Cleveland, Ohio, consulted a group of eighth-graders when she asked them the question: “What do you understand by the classics in literature?” Two of the answers Clark received were “Classics are books your fathers give you and you keep them to give to your children” and “Classics are those great pieces of literature considered worthy to be studied in English classes of high school or college”.
In the 1980s Italo Calvino said in his essay “Why Read the Classics?” that “A classic is a book that has never finished saying what it has to say.” 
It would be safe to say that a classic would be a book that could outlast the time in which it was written.
