I am most thankful to the many students in my qualitative research methods classes at the University of Nebraska–Lincoln who helped to shape this book over the years. They offered suggestions, provided examples, and discussed the material in this book. Also, I benefited from capable scholars who helped to shape and form this book in the first edition: Paul Turner, Ken Robson, Dana Miller, Diane Gillespie, Gregory Schraw, Sharon Hudson, Karen Eifler, Neilida Aguilar, and Harry Wolcott. Ben Crabtree and Rich Hofmann helped form the first edition text significantly and encouraged me to proceed, and they diligently and timely responded to Sage’s request to be first edition external reviewers. In addition, Keith Pezzoli, Kathy O’Byrne, Joanne Cooper, and Phyllis Langton served as first edition reviewers for Sage and added insight into content and structure that I could not see because of my closeness to the material. To the reviewers for this third edition, I appreciate your time and effort reviewing the draft of my book. As always, I am indebted to C. Deborah Laughton, who served as my acquisition editor for the first edition, to Lisa Cuevas Shaw who served as editor for the second edition, and to Vicki Knight who helped as acquisition editor for this third edition. Also for all of the editions, members of the Office of Qualitative and Mixed Methods Research (OQMMR) all provided valuable input. I especially single out Dr. Vicki Plano Clark, Dr. Ron Shope, and Yuchun Zhang who have been instrumental in refining and shaping my ideas about qualitative research through these several editions. Also, I am grateful to the Department of Educational Psychology. Finally, to members of my family—Karen, David, Kasey, Johanna, and Bonny—thanks for providing me with time to spend long hours writing and revising this book. Thank you all.
