In the years since the first edition of Controversies in Second Language Writing was published, there been little to no clear resolution of the controversies Casanave so accessibly and fair-mindedly laid out. In fact, many of them have become far more complex and intertwined with many other 21st century issues that teachers of L2 writing cannot help but be affected by in their classrooms. Therefore, this second edition has set out to address: What issues if any have been resolved? What issues have had lasting power from the past, either because people are resistant to change or because the issues continue to be unresolved ones that writing teachers and scholars need to keep discussing?

The second edition is a thorough revision with all chapters updated to refer to works written since the first edition was published. A few chapters have been added: one devoted to writing in a digital era (Chapter 3); one devoted to the debates about English as a lingua franca, "translingual literacy practices," and other hybrid uses of English that have been ongoing in the last ten years (Chapter 4); and one giving special attention to issues related to writing from sources and plagiarism (Chapter 6).

As with the first edition, the second edition of Controversies is not a book that will teach readers how to do things. Rather, it is a book designed to help readers think and to wrestle with issues in L2 writing that are not easily resolved by how-to prescriptions.
