Talk, Tools, and Texts tackles a perplexing issue: how can we envision writing as developing throughout a lifetime, from the first purposeful marks made on paper to the last? How can we make accounts of writing development that keep the complexity of our lives in mind while also providing useful insight to researchers, teachers, and writers?Drawing on eleven accounts of writers at different points in the lifespan (ages 12 to 80) and in different social circumstances (from a middle-school classroom to a bird-sanctuary newsletter), Talk, Tools, and Texts constructs a “logic-in-use” for following writers and their writing development at a variety of points in the lifespan. It also offers several strategies scholars can use in pursuit of their own research into lifespan writing.
