.The title of each book is the first instrument for acquainting the reader with the content and author of the book .It is clear that there's a mutual relation between historical , social and political events of each era with literary events and it affects directly on poets' mind and language .In this study ,we present lots of contemporary poem books , and describe the important literary, historical ,social and political events of each era ,and find a relation between the poem book titles and dominant events regardless of the book content and show this mutual effect in the structure ,content and rhetoric .In general , in terms of structure , titles change from one word and noun group into several sentence and even alphabet letters .In terms of rhetoric , the literal and apathetic titles of the book change into creative ,poetic and empathetic titles .As a result , amphibology and abstraction are created .In terms of content ,the extremist patriotic and static titles change into social ,religious ,political and revolutionist idealism .Finally , lots of meaningless words are created .
