Acknowledgments Thank you to our colleagues and friends at McIntyre Library and the University of Wisconsin–Eau Claire. If you are bemused by our enthusi- asm for surveys, you are gracious editors, testers, and analysts. Thank you, also, to our survey respondents—you have taught us more than you know. A special thanks to our director, Jill Markgraf, for supporting us in this project. And to our colleagues Hans Kishel, Eric Jennings, and Jenna Vande Zande, for stepping in for us when we needed to work on this book.
