Welcome to the Purdue OWL
If you are having trouble locating a specific resource, please visit the search page or the Site Map.
The Online Writing Lab (OWL) at Purdue University houses writing resources and instructional material, and we provide these as a free service of the Writing Lab at Purdue. Students, members of the community, and users worldwide will find information to assist with many writing projects. Teachers and trainers may use this material for in-class and out-of-class instruction.
For more information about services for the Purdue University community, including one-to-one consultations, ESL conversation groups and workshops, please visit the Writing Lab site.
