If They Give You Lined Paper, Write Sideways

If They Give You Lined Paper, Write Sideways is a book by Daniel Quinn, author of "Ishmael". It is presented as a dialog between Quinn and a reader of his books, and is intended to answer the question, "How do you do what you do?"
The title is quite similar to a quotation to Juan Ramón Jiménez (24 December 1881 – 29 May 1958): "If they give you ruled paper, write the other way."
