Is a ” found poem” where instead of gathering found lines, you gather books and stack them in such a way that the book spines comprise a poem.
To make a book spine poem, you would start by moving these books around into stacks with the spines together so that the titles are like the lines of a poem. You would keep moving the book titles around into different stacks until you find the “lines” that go best together to make a poem.
