Against the backdrop of a longstanding practice of ÔerasureÕ both in artistic and critical work, co-guest editors Paul Benzon and Sarah Sweeney take up challenging questions related to the aesthetics of erasure today in the digital era. They investigate new meanings and the relevance of said practice within twenty-first century contemporary contexts typically defined by digital knowledge production, preservation, and sharing. Contributing authors give expression to five sites of inquiry mapped by the editors within the expansive practice of erasure Ð Power, Capital, Signal and Noise, Technology and Archive.
