danah boyd (she doesn’t capitalize her name) is a Principal Researcher at Microsoft Research and a Fellow at Harvard’s Berkman Center, where she looks at how young people use social media as part of their everyday lives. She has a new book out called It’s Complicated: The Social Lives of Networked Teens, and she’s made it available as a free PDF. On her website she writes, “I didn’t write this book to make money. I wrote this book to reach as wide of an audience as I possibly could. This desire to get as many people as engaged as possible drove every decision I made throughout this process. One of the things that drew me to Yale [the publisher] was their willingness to let me put a freely downloadable CC-licensed copy of the book online on the day the book came out.” But she also asks that you purchase a copy of the book if you find it useful. “Your purchasing decisions help me signal to the powers that be that this book is important, that the message in the book is valuable.” Find the PDF here, or in our collection of Free eBooks.
