The best-selling new composition book published in this century, in use at more than 1,000 schools, They Say / I Say has essentially defined academic writing, identifying its key rhetorical moves, the most important of which is to summarize what others have said ("they say") to set up one's own argument ("I say"). The book also provides templates to help students make these key moves in their own writing.The Second Edition includes a new chapter on reading that shows students how to read for the larger conversation and two new chapters on the moves that matter in the sciences and social sciences.
