The European Journal of Research and Development (EJRND, e-ISSN 2822-2296), published by Orclever Science & Research Group, is a diamond open-access journal (free to read for everyone, free to publish for authors) that operates under both green and gold open-access models. Authors retain full copyright, articles are published under CC BY 4.0, and every author is actively encouraged to self-archive their work in as many repositories as possible — with no embargo, no fee, and no need to ask permission.

This page is the authoritative EJRND statement of self-archiving rights, intended for authors, institutional repository managers, funder-compliance officers, DOAJ & Sherpa Romeo curators, and indexing services.

1. Which article versions may be self-archived

Three distinct versions of every EJRND article exist. All three may be freely self-archived:

1.1 Preprint (submitted version)

The manuscript as originally submitted to EJRND, before peer review. Authors may post it:

• before submission (e.g. on arXiv / SSRN / bioRxiv);
• during peer review;
• any time after publication.

Because the preprint is authored entirely by the authors and contains no editorial contribution by EJRND, no permission is required and no version restrictions apply.

1.2 Postprint (accepted manuscript, AAM)

The peer-reviewed, author-prepared version after referees' comments have been addressed, but before typesetting by Orclever. Authors may deposit the AAM in any repository immediately upon receiving their acceptance letter. We recommend including a cover page that states:

“This is the accepted manuscript of the article published as: [full citation with DOI]. Licensed under CC BY 4.0.”

1.3 Version of record (VOR, published version)

The final typeset PDF as published on www.orclever.com/journals/ejrnd. Because CC BY 4.0 is irrevocable, authors are free to deposit the VOR PDF in any repository at any time, including commercial platforms. No embargo applies.

2. Where articles may be self-archived

There is no restricted list. All of the following are explicitly allowed and encouraged:

2.1 Preprint servers

• arXiv (physics, math, CS, quant-finance, stats, EE-SS, econ, bio)
• bioRxiv (biology)
• medRxiv (medicine, public health)
• SSRN (social sciences, law, economics)
• engrXiv (engineering)
• ChemRxiv (chemistry)
• OSF Preprints (multi-disciplinary)
• Preprints.org (MDPI, multi-disciplinary)

2.2 Institutional repositories

The author's university, research institute, or funder repository. Examples:

• Aperta (TÜBİTAK, Turkey)
• DergiPark affiliate repositories (TÜBİTAK ULAKBİM)
• HAL (CNRS & French universities)
• Zenodo communities run by institutions
• Any DSpace, EPrints, Figshare for Institutions, Invenio, or Samvera-based repository.

2.3 Subject repositories

• PubMed Central (PMC) — biomedical
• RePEc — economics
• PhilPapers — philosophy
• CogPrints — cognitive sciences
• LILACS — Latin American & Caribbean biomedical
• ERIC — education

2.4 Generic research repositories

• Zenodo (CERN) — also the backup deposit target for EJRND itself; see our archiving policy
• Figshare
• Dryad — for datasets associated with EJRND articles
• Open Science Framework (OSF)

2.5 Academic social networks

• ResearchGate
• Academia.edu
• Mendeley

2.6 Personal & lab websites

Personal homepages, group/lab sites, course pages, teaching materials, theses, dissertations, and any other non-commercial or commercial website.

2.7 Orclever-run archives (automatic, no author action needed)

In addition to any author-initiated deposits, every published EJRND article is automatically:

• Submitted to the Internet Archive Wayback Machine (permanent snapshot of HTML landing page and PDF).
• Deposited on Zenodo — Orclever community with its own Zenodo DOI, alongside the journal's Crossref DOI.
• Preserved in Orclever's own encrypted off-site platform backups (disaster recovery only).

See the full archiving policy for details.

3. Embargo

EJRND enforces zero embargo. All versions may be self-archived immediately:

• Preprint — before, during, or after peer review.
• Postprint (AAM) — on the day the acceptance letter is issued.
• Version of record — on publication day.

4. Licence on self-archived copies

Every article in EJRND is licensed CC BY 4.0. Because CC BY 4.0 is a standing, irrevocable licence from the author to the public, every self-archived copy automatically carries the same terms — reuse, remixing, commercial use, and translation are all permitted, provided the original article is cited.

When depositing in a repository that asks for a licence declaration, please state “CC BY 4.0” or, equivalently, “Creative Commons Attribution 4.0 International”.

5. Required attribution on deposits

Every self-archived copy must include a visible citation to the published version. The minimum acceptable citation includes:

• all authors in submission order,
• the article title,
• journal name: The European Journal of Research and Development,
• year, volume, issue (or article number), and page range where applicable,
• the Crossref DOI, as a clickable https://doi.org/… link, and
• a link to the version of record on the journal website.

Each EJRND article's landing page provides one-click export of this citation in BibTeX, RIS, and plain-text formats. A recommended text template is:

Author, A., Author, B., & Author, C. (Year). Title of the article. The European Journal of Research and Development, V(I), pp–pp. https://doi.org/10.xxxx/xxxx. Published open access under CC BY 4.0. Available at: https://www.orclever.com/journals/ejrnd/article/[id].

6. Funder / mandate compliance

EJRND's combination of CC BY 4.0, retained author copyright, zero embargo, and unrestricted repository deposit satisfies the open-access mandates of all major funders the journal's authors are likely to encounter:

6.1 TÜBİTAK Open Science Policy (Turkey)

CC BY 4.0 is explicitly accepted; deposit in Aperta or institutional repository is permitted. ✓

6.2 Plan S / cOAlition S

CC BY 4.0 required, no embargo, VOR deposit permitted. ✓

6.3 European Commission (Horizon Europe, Horizon 2020)

Immediate open access with CC BY (or CC BY-SA, CC0) required. ✓

6.4 NIH Public Access Policy (USA)

Postprint or VOR deposit in PubMed Central. EJRND allows this without embargo. ✓

6.5 UKRI (UK Research & Innovation)

CC BY required, zero embargo, VOR deposit allowed. ✓

6.6 Wellcome Trust

CC BY required, immediate deposit in Europe PMC. ✓

6.7 Gates Foundation

CC BY, zero embargo, VOR deposit in CHORUS or PMC. ✓

6.8 ERC (European Research Council)

Compliant with Plan S; CC BY 4.0 is the default. ✓

7. Preprint → VOR linking (Crossref)

If an author posted the preprint on a server that issues a preprint DOI (e.g. bioRxiv, arXiv, SSRN, Zenodo), the preprint DOI should be declared during submission. EJRND then registers the preprint → VOR relationship in Crossref using the is-preprint-of metadata field, so indexing services, funder tools, and search engines can follow the trail from the first draft to the version of record.

8. Dataset / code deposits

Authors are strongly encouraged to deposit supplementary datasets and code in a recognised research data repository (Zenodo, Figshare, Dryad, OSF, GitHub + Zenodo integration, etc.) and cite the dataset DOI in the article. Data and code deposits are covered by the same CC BY 4.0 terms unless a different licence is specified by the author at deposit time (recommended: CC0 for pure data, MIT or Apache-2.0 for source code).

9. Sherpa Romeo & DOAJ registration

EJRND is being registered with Sherpa Romeo to make these self-archiving terms machine-discoverable by institutional repository managers, funder-compliance tools (FACT, Cottage Labs Publications Router, etc.), and DOAJ. Until the Sherpa Romeo record is fully published, this page is the authoritative statement of the journal's policy.

10. How to ask for help

Questions about self-archiving, funder compliance, institutional repository deposits, or specific preprint servers can be sent to the EJRND editorial office at editorial@orclever.com. Please include:

• the DOI (or article title) of the paper in question,
• the name of the repository / funder / mandate, and
• the specific question (e.g. "does CC BY 4.0 satisfy Plan S?" → yes, it does).
