Living Books About Life is a series of curated, open access books about life -- with life understood both philosophically and biologically -- which provide a bridge between the humanities and the sciences. Produced by a globally-distributed network of writers and editors, the books in the series repackage existing open access science research by clustering it around selected topics whose unifying theme is life. All the books in the series are themselves ‘living’, in the sense that they are open to ongoing collaborative processes of writing, editing, updating, remixing and commenting by readers.
