As James Longenbach writes in The Art of the Poetic Line, “Line has no identity except in relation to other elements in the poem, especially the syntax of the poem’s sentences. It is not an abstract concept, and its qualities cannot be described generally or schematically. It cannot be associated reliably with the way we speak or breathe. Nor can its function be understood merely from its visual appearance on the page.” Printed books altered our relationship to poetry by allowing us to see the lines more readily. What new challenges do electronic reading devices pose?
