Dominick LaCapra is one of the best-known critics of literature and art that is engaged with the Holocaust and of the Holocaust and post-Holocaust eras.
This book is not a book of history, though it is bound up with a historical event, nor is it a literary work. Instead, it is analysis of some major works of literature and art of the Holocaust and post-Holocaust eras. LaCapra provides concise and well thought-out analysis of The Fall, by French philosopher Albert Camus, Claude Lanzmann's unforgettable must-see documentary about the Holocaust (you will never forget it, and you MUST see it if you wish to understand something about the Holocaust, or Shoah, in Hebrew), and Art Spiegelman's Maus, a unique cartoon-art chronicle about his own father's life and experiences in the Auschwitz concentration camp.
A useful companion title is Testimony: Crises of Witnessing in Literature, Psychoanalysis and History, by Shoshana Felman and Dori Laub. Felman also has an article on Camus' The Fall, and one on Lanzmann's Shoah. For another article on Maus, see Marianne Hirsch's article in Discourse 15:2, Winter 1992-1993 pp.3-29 entitled,"Family Pictures: Maus, Mourning and Post-Memory."
LaCapra's first two chapters in this book are especially useful, as is his introduction and excellent discussion of the Historikerstreit in Representing the Holocaust: History, Theory, Trauma. This particular work is not a book to skip, even if you ultimately don't agree with all its conclusions.
For more on the Holocaust and literature on and of the Holocaust, see authors such as Sidra Ezrahi, Lawrence Kritzman, Berel Lang, Pierre Nora, and Geoffrey Hartman.
