Intertextuality refers to both implicit and explicit references to other texts in a text. It has been said that a writer writes all of his texts on the basis of other books he has read, or perhaps based on his entire life experience. On the other hand, from the reader's point of view, it can be said that all texts are always interpreted in relation to some of the texts that precede them and in relation to the reader's life experience and situation. Thus, intertextual references can be observed in all literature and in culture in general.
