Deciphering Human Chromosome 16: We Report Here, and Deciphering Human Chromosome 16: Index to the Report, by Sarah Jacobs, use text in a visual way to document the ethical, economic, political and philosophical polemics associated with mapping the human genome. The Report is an ebook which contains links to over 240 websites collected in the months following publication in the journal Nature of ¿The sequence and analysis of duplication-rich human chromosome 16¿ ( Vol. 432. December 2004). Its contents change over time as the websites change, migrate or disappear. It is available as a FREE DOWNLOAD from the publisher at www.informationasmaterial.com .The Index sets fragments collected from the websites against the background of the earlier draft sequence originally published by Project Gutenberg. The solid physicality of the Index contrasts with the ever changing Report although vagaries of the printing process ensure that each copy of the Index is unique.
