A Message from the Coordinator:

Oct. 4, 2019: OWL Staff are hard at work on new resources that will cover the updates in the latest edition of the APA Publication Manual. We're excited to share these with you soon. We tentatively expect to have the pages finished by the end of the fall semester. 

Thank you for your patience as we work to get these resources out. The messages of anticipation and excitement we've been receiving from our readers lately have been genuinely touching.

All the best.


Spotlight Resource

Oct. 10, 2019:  Many thanks to the OWL's Maggie Myers for starting our Style Manual Glossary. This resource explains the research, citation, and style terminology you've always wanted to learn, but were too afraid to ask about. Look for additional entries to be added in the future!

Past spotlight resources can be found here.
