My discipline already has a practice of publishing preprints in Open Access, disciplinary repositories (e.g., arXiv). Do we need to do anything differently because of the UNT Open Access Policy?

No. The UNT Open Access Policy refers to the accepted manuscripts and versions of record (see Policy for full definitions). Faculty members may continue to publish their preprints as they have been doing. There is no requirement for duplicate submissions of preprints in the UNT Scholarly Works repository, but faculty members are encouraged to deposit their preprints at UNT if they desire.
