For the Copy Left, as for Hyde, the last 20 years have witnessed a corporate “land grab” of information — often in the guise of protecting the work of individual artists — that has put a stranglehold on creativity, in increasingly bizarre ways. Over dinner not long ago, he told me about the legal fate of Emily Dickinson’s poems. Dickinson died in 1886, but it was not until 1955 that an “official” volume of her collected works was published, by Harvard University Press. The length of copyright terms has expanded substantially in the last century, and Harvard holds the exclusive right to Dickinson’s poems until 2050 — more than 160 years after they were first written. When the poet Robert Pinsky asked Harvard for permission to include a Dickinson poem in an article that he was writing for Slate about poetic insults, it refused, even for a fee. “Their feeling was that once the poem was online, they’d lose control of it,” Hyde told me.
