A classic is a book that has never finished saying what it has to say.

A classic is a book that doesn't have to be written again.

A classic is the term given to any book which comes to represent the whole universe, a book on a par with ancient talismans.

Definition of a classic — something that everybody wants to have read and nobody wants to read.

A classic,' suggested Anthony, 'is a successful book that has survived the reaction of the next period or generation. Then it's safe, like a style in architecture or furniture. It's acquired a picturesque dignity to take the place of its fashion.

1 )Classics are books which, the more we think we know them through hearsay, the more original, unexpected, and innovative we find them when we actually read them.
2)A classic is a work which constantly generates a pulviscular cloud of critical discourse around it, but which always shakes the particles off.

A classic is something that everybody wants to have read and nobody wants to read.

“Classic.” A book which people praise and don't read.

Classics are books everyone knows but no has read.

There are no 'classics' of crime and detection. Not one. Within its frame of reference, which is the only way it should be judged, a classic is a piece of writing which exhausts the possibilities of its form and can never be surpassed. No story or novel of mystery has done that yet. Few have come close. Which is one of the principal reasons why otherwise reasonable people continue to assault the citadel.

The relationship we develop with a classic is like a lifelong friendship: it goes through ups and downs. Whenever we reopen the book, we are different, and, as a result, what we read is too. This, I think, is another definition of a literary classic: like a mirror, it reflects what is in front of it.

What is a classic? Is a classic a book that stays in print? Who decides what stays in print, what gets remaindered, what makes it into paperback, onto the supermarket displays, back into hardbound collected works? Alice Walker's first novel, The Third Life of Grange Copeland, was out of print for seven years. It didn't change. By what mechanism is it now available in paperback? Pat Parker's Movement In Black is out of print, as is Barbara Deming's work. How might their work come back to us? By their deaths? "Discovery" by an influential critic? In fact, much of the work of Aphra Behn, Emily Dickinson, Christina Rossetti, Angelina Weld Grimké, Willa Cather, Gertrude Stein, H.D., and others, was out of print or hard to come by prior to the second wave of feminism (and who knew that all of these women loved women!) Is this work classic now, but not then? Can we only talk about classics after a suitable passage of time?

The word (classical) carries the implication that the works of art and literature produced in Graeco-Roman antiquity possess an absolute value, that they form the standard by which all others are to be judged.

1. The classics are those books about which you usually hear people saying: ‘I’m rereading…’, never ‘I’m reading…’ At least this is the case with those people whom one presumes are ‘well read‘; it does not apply to the young, since they are at an age when their contact with the world, and with the classics which are part of that world, is important precisely because it is their first such contact. The iterative prefix ‘re-’ in front of the verb ‘read’ can represent a small act of hypocrisy on the part of people ashamed to admit they have not read a famous book. To reassure them, all one need do is to point out that however wide-ranging any person’s formative reading may be, there will always be an enormous number of fundamental works that one has not read.
