Supporting Open and Accessible Scholarly Publishing

At Colloquys Publishing, we believe that scholarly knowledge should be freely accessible to researchers, educators, professionals, policymakers, and the wider global community. To ensure unrestricted access to published research, all articles are published under an open-access model, allowing readers worldwide to access, read, download, and share content without subscription barriers.

To support the editorial, production, technological, and preservation services involved in scholarly publishing, Colloquys Publishing applies an Article Processing Charge (APC) for manuscripts that are accepted following peer review.

No fees are charged for manuscript submission, initial editorial screening, or peer-review evaluation. APCs become payable only after a manuscript has successfully completed the review process and has been formally accepted for publication.


What the Publication Fee Supports

The Article Processing Charge contributes to the professional services required to publish and maintain high-quality scholarly content, including:

  • Preliminary editorial assessment
  • Manuscript processing and workflow management
  • Single-blind peer-review administration
  • Research integrity and plagiarism screening
  • Language and technical quality checks
  • Article formatting and production preparation
  • Online publication and website hosting
  • Long-term digital preservation and archiving
  • Search engine optimization and article discoverability
  • Indexing support and metadata dissemination
  • Post-publication maintenance and corrections

These services ensure that accepted manuscripts are published efficiently, professionally, and remain permanently accessible to the scholarly community.
