Back in mid-2013, Paul Heald posted to SSRN a short paper that already has had far more impact than academic papers usually have on the public debate over copyright policy. That paper, How Copyright Makes Books and Music Disappear (and How Secondary Liability Rules Help Resurrect Old Songs), employed a clever methodology to see whether copyright facilitates the continued availability and distribution of books and music. Encouraging the production of new works is, of course, copyright’s principal justification. But some have contended that copyright is also necessary to encourage continued exploitation and maintenance of older works. We find an example in the late Jack Valenti, who, as head of the Motion Picture Association of America, in 1995 made the argument before the Senate Judiciary Committee that it was necessary to extend the copyright term in part to provide continued incentives for the exploitation of older works. “A public domain work is an orphan,” Valenti testified. “No one is responsible for its life.” And of course if no one is responsible for keeping a creative work alive, it will, Valenti suggests, die.
Is that argument right? Enter Paul Heald. Heald’s 2013 article employs a set of clever methodologies to test whether copyright did, indeed, facilitate the continued availability of creative works—in Heald’s article, books and music. With respect to books, Heald constructed a random sample of 2300 books on Amazon, arranged them in groups according to the decade in which they were published, and counted them. Here are his findings: Continue reading "How Copyright Prevents Us From Getting the Books We Want"
