Interviewing Users published by Rosenfeld.
Chapter two of this useful book (where you'll find DD+D p,16) talks about the importance of empathy and interviewing. Stressing the need for design researchers to check-in with their own biases and assumptions before hitting the field.
This marks the second time that DD+D's work has been referenced in a book. The first being "Outside In" published by Forrester Research
