This report outlines the history of the Purdue Online Writing Lab (OWL) and details the OWL Usability Project through the summer of 2006. The paper also discusses test methodologies, describes test methods, provides participant demographics, and presents findings and recommendations of the tests. The purpose of this report is to provide researchers, administrators, and pedagogues interested in usability and Writing Labs access to information on the Purdue OWL Usability Project. We hope our findings—and this open source approach to our research—will contribute positively to the corpus on usability and Writing Lab studies.
