Existentialist literature is a genre that explores the meaning and purpose of human existence, often through the lens of individual experience and subjective perception. These books often delve into themes of freedom, choice, and responsibility, and may challenge traditional notions of morality and societal norms. Existentialist literature can be introspective and philosophical, and may offer readers a unique perspective on the human condition and the search for meaning in a complex and often chaotic world.

The "Experimental" category of books is characterized by works that challenge traditional literary conventions and push the boundaries of form and content. These books often incorporate unconventional narrative structures, language, and themes, and may experiment with different mediums such as poetry, visual art, or multimedia. The goal of experimental literature is to create new and innovative ways of storytelling that challenge readers' expectations and expand the possibilities of what literature can be.
