Open Access & Licensing Policy

All research articles published by Opus Publica are immediately, freely, and permanently available to read, without subscription, paywall, or registration. We believe public policy research is most valuable when it can be read, shared, and built upon by the widest possible audience — including the policymakers, advocates, and communities it concerns.

Unless otherwise stated on a specific journal's page, all articles published by Opus Publica are distributed under the Creative Commons Attribution 4.0 International License (CC BY 4.0).

The full legal text of this license is available at: https://creativecommons.org/licenses/by/4.0/

Under this license, anyone is free to:

• Share — copy and redistribute the material in any medium or format
• Adapt — remix, transform, and build upon the material for any purpose, including commercially

The only requirement is attribution: you must give appropriate credit to the original author(s), provide a link to the license, and indicate if changes were made. This can be done in any reasonable manner, but not in any way that suggests the author or Opus Publica endorses you or your use.

No additional restrictions may be applied that would prevent others from exercising the rights the license grants.

Authors who publish with Opus Publica retain full copyright of their work. By submitting, authors grant Opus Publica a non-exclusive license to publish the work under the terms above; authors remain free to also publish their own work elsewhere, deposit it in institutional or subject repositories, or share it freely, provided the published version and its DOI are appropriately cited.

Opus Publica is a Diamond Open Access publisher. We charge no fees to authors at any stage of the publication process — no submission fee, no article processing charge (APC), and no fee upon acceptance or publication. Readers likewise access all published content free of charge, with no subscription or paywall. Publication costs are covered by Advocacy Unified Network, not by authors or readers.

Each Opus Publica journal displays its specific license and this policy on its own "Aims & Scope" page. In the rare case a journal uses different licensing terms than CC BY 4.0, that journal's own page will state so explicitly; this page reflects the standard, default policy across the publishing house.

Authors are encouraged to deposit the published version of their article (with DOI) in their institution's repository or a subject-specific repository such as SSRN, immediately upon publication, consistent with the terms of the CC BY license.

This policy is provided to comply with DOAJ, Crossref, and other indexing bodies' requirements for a clear, stable statement of licensing terms.
