Put simply, this volume is absolutely indispensable for anyone engaged in ISLA research. Two of the world’s most accomplished and renowned ISLA scholars, Laura Gurzynski-Weiss and YouJin Kim, and the incredible cast of contributing authors they’ve brought together are setting the new standard for empiricism in ISLA. Deftly aligning substantive and methodological considerations, this text answers every question you ever had about ISLA methods and every question you never thought to ask. Just one question remains: How did ISLA make it this far without this book?
