This article presents some experiments that took place in the U.S and we can say foreshadowed a new paradigm in the research on the history of literature. „A New Literary History of America” (2009, 2012, coordinators Greil Marcus and Werner Sollors) is a collection of over 200 essays written by various specialists: researchers and journalists. These essays are dedicated to the most important cultural events that influenced American literature in last 250 years. The new history of literature is presented as a kaleidoscope of ideas and images Made in US. Everything seems to be important: novels related to „high culture” written by Faulkner or Salinger, and cartoon movies with Mickey Mouse, journals, travel notes, philosophical essays, comics, scripts for movies and radio, country songs, blues, rock, jazz, hip-hop etc., so that the work is a collective, polyphonic and heteroglossia epic of U.S. culture. David Wyatt knows how to reconcile the academic requirements of the market with a history of literature entitled „Secret Histories: Reading Twentieth-Century American Literature” (Baltimore, 2010). „Hidden stories” that Wyatt makes known have provocative potential, arouse discussions, and start the dialogue of interpretations. The themes of the dialogues aim at human relationships: interethnic, love, family between and society, between worker and employer, etc. Literary history conceived as a dialogue of voices, opinions, associations, ideas and styles leaves the field of fixed portraits and makes “all American speech” move.
