Teachers and trainers may use this material for in-class and out-of-class instruction.

The Purdue University Writing Lab and Purdue Online Writing Lab (OWL) assist clients in their development as writers—no matter what their skill level—with on-campus consultations, online participation, and community engagement. The Purdue Writing Lab serves the Purdue, West Lafayette, campus and coordinates with local literacy initiatives. The Purdue OWL offers global support through online reference materials and services.

A Message from the Coordinator:

Dec. 4, 2019: Our new pages covering the recently-released Publication Manual of the American Psychological Association, Seventh Edition are taking a little longer than anticipated, unfortunately. We're now aiming for an early spring 2020 launch date for the new APA 7 pages.

Thank you again for your patience. We at the OWL take this work seriously, and it's been an honor to receive messages of anticipation from students, teachers, and administrators all over the world these past few months.

All the best.
