Software studies is an emerging interdisciplinary research field, which studies software systems and their social and cultural effects. The implementation and use of software has been studied in recent fields such as cyberculture, Internet studies, new media studies, and digital culture, yet prior to software studies, software was rarely ever addressed as a distinct object of study. To study software as an artifact, software studies draws upon methods and theory from the digital humanities and from computational perspectives on software. Methodologically, software studies usually differs from the approaches of computer science and software engineering, which concern themselves primarily with software in information theory and in practical application; however, these fields all share an emphasis on computer literacy, particularly in the areas of programming and source code. This emphasis on analysing software sources and processes (rather than interfaces) often distinguishes software studies from new media studies, which is usually restricted to discussions of interfaces and observable effects.
