The Journal of Open Source Software
The Journal of Open Source Software (JOSS) is a developer friendly, open access journal for research software packages.
What exactly do you mean by 'journal'
The Journal of Open Source Software (JOSS) is an academic journal (ISSN 2475-9066) with a formal
peer review process that is designed to improve the quality of the software submitted.
Upon acceptance into JOSS, a CrossRef DOI is minted and we list your paper on the JOSS website.
Don't we have enough journals already?
Perhaps, and in a perfect world we'd rather papers about software weren't necessary but we
recognize that for most researchers, papers and not software are the currency of academic research
and that citations are required for a good career.
We built this journal because we believe that after you've done the hard work of writing great
software, it shouldn't take weeks and months to write a paper about your work.
You said developer friendly, what do you mean?
We have a simple submission workflow and extensive documentation to help you prepare your
submission. If your software is already well documented then paper preparation should take no
more than an hour.
You can read more about our motivations to build JOSS in our
announcement blog post.
Code of Conduct
Although spaces may feel informal at times, we want to remind authors and reviewers (and anyone else) that this is a professional space. As such, the JOSS community adheres to a code of conduct adapted from the Contributor Covenant code of conduct.
Authors and reviewers will be required to confirm they have read our code of conduct, and are expected to adhere to it in all JOSS spaces and associated interactions.
We also want to remind authors and reviewers (and anyone else) that we expect and require ethical behavior. Some examples are:
- All authors are obliged to provide retractions or corrections of any mistakes of which they become aware.
- Plagiarism (e.g., violation of another author's copyright), for both software and papers, is not allowed.
- Self-plagiarism (repeated publication of the same work) is not allowed.
- Author lists must be correct and complete. All listed authors must have made a contribution to the work, and all significant contributors should be included in the author list.
- Reviews should be accurate and non-fraudulent. Examples of concerns are: Authors should not suggest reviewers who are not real people or have conflicts. Reviewers and editors must disclose conflicts. Bribes for authors, reviewers, editors are not permitted.
Any potentially unethical behavior should be brought to the attention of the JOSS staff.
See Contacting JOSS.
The JOSS Editors will track any concerns and respond to the submitter with a resolution, which will range from doing nothing if the editors disagree about the issue to withdrawing papers and notifying authors' institutions.

Cost and Sustainability Model
The Journal of Open Source Software is an open access journal committed to running at minimal costs, with zero publication fees (article processing charges) or subscription fees.
Under the NumFOCUS nonprofit umbrella as part of Open Journals, JOSS is eligible to seek grants for sustaining its future. With an entirely volunteer team, JOSS is seeking to sustain its operations via donations and grants, keeping its low cost of operation and free service for authors.
In the spirit of transparency, below is an outline of our current running costs:
- Annual Crossref membership: $275 / year
- JOSS paper DOIs: $1 / accepted paper
- JOSS website hosting (Heroku): $19 / month
Assuming a publication rate of 200 papers per year this works out at ~$3.50 per paper ((19*12) + 200 + 275) / 200 .
