Ulises Carrión, 1979:
A book is a sequence of spaces.
Each of these spaces is perceived at a different moment—a book is also a sequence of moments.
A book is not a case of words, nor a bag of words, nor a bearer of words.
A writer, contrary to the popular opinion, does not write books.
A writer writes texts.
Carrión’s perspective on the form of the book de-emphasises any inherent union between the material form of the book and its printed contents, and implies that each body of material to be made into a book must somehow be addressed to the display conditions that the book offers.
