With nine chapters on theories and 10 chapters on methods, all contributed by knowledgeable professionals, Theories and Methods of Writing Center Research: A Practical Guide, edited by Jo Mackiewicz & Rebecca Day Babcock, is the research guide I have been waiting for. I have previously conducted two IRB-approved studies on writing centers and am in the middle of my third; without this guide, I have had to pull from multiple sources and have tried to read between the lines of published articles to determine the theories, methods, and methodologies that might best suit a writing center-specific context as a site for inquiry. While I will still turn to multiple sources while designing any research study and still encourage others to do so as well, this collection offers a starting place to ground research projects within the field of writing center studies.
