"This volume of twenty studies selected from the over 500 presentations from the IVth Writing Research Across Borders Conference in Bogotá, Colombia continues the tradition of publication of selected papers from each of the conferences. While each of the conferences and consequent volumes were open to the wide range of best current research on writing, strong themes emerged, reflecting the evolution of the conference, the sponsoring International Society for the Advancement of Writing Research, and the broader development of the international writing research community." -- Introduction.
