An Empirical Analysis of Planned Obsolescence: Textbooks!

A study by Toshiaki Iizuka wherein he examines the motivations for publishers to release new editions of textbooks. He finds data to support the idea that "publishers introduce new editions to kill-off used units"; however, he also says that "publishers' frequent revisions cannot be attributed to planned obsolescence alone".
