All periodicals published by the Institute of Archaeology and Ethnology of the Polish Academy of Sciences are reviewed and they declare strict adherence to the highest standards of ethics for publications based on principles advocated by the international organization Committee on Publication Ethics (COPE, cf. ), as well as the principles of the Code of Conduct in Academic Practice. All articles not in accordance with these standards will be removed from the publication if malpractice is discovered at any time even after the publication. In accordance with the code of conduct we will report any cases of suspected plagiarism or duplicate publishing. 

Authors must ensure that they have written original works. In addition they must ensure that the manuscript has not been issued elsewhere. Any work or words of other authors, contributors, or sources should be appropriately credited and referenced. Authors submitting their works to the journal for publication as original articles confirm that the submitted works represent their authors' contributions and have not been copied or plagiarized in whole or in part from other works without clearly citing. All authors should disclose financial or other conflict of interest that might influence the results or interpretation of their manuscript (financial support for the project should be disclosed). When an author discovers a significant error or inaccuracy in his/her own published work, it is the author's obligation to promptly notify the journal editor and cooperate with the editor to retract or correct the paper. Submitting a paper simultaneously to more than one publication at a time is a breach of publications ethics. 

Editors must ensure a fair blind peer-review of the submitted articles for publication. They will strive to prevent any potential conflict of interests between the author and editorial and review personnel. Editors will also ensure that all the information related to submitted manuscripts is kept as confidential before publishing. 
The authors are obliged to disclose the participation of third parties in the creation of the text; the responsibility for complying with this duty rests chiefly with the author submitting the text. If the lack of scholarly diligence in the form of ghostwriting or guest authorship is detected, the Board of Editors is obliged to apprise the academic milieu of this infringement of professional ethics.

The Board of Editors makes a preliminary selection of articles in relation to their conformity with the thematic profile and the formal requirements of the periodical and with the standards of scholarly publication. Subsequently the articles are forwarded to outside reviewers. The process of reviewing texts submitted to JUE follows the double-blind review rule, i.e. the identities of the authors are unknown to the reviewers and vice-versa; in other cases, the reviewer signs a statement on the absence of a conflict of interests. The reviewed aspects are: the concept of the study (choice of topic, assumptions), its methodology (selection and application of the method of analysis), the narration (clarity of argumentation, appropriateness of style) and editorial correctness (suitable title, division into subsections, footnotes). The reviewer submits his/her opinion in writing, stating the reasons for the article’s rejection or the conditions that must be met for it to be accepted for publication.

The author is requested to comment on the reviewer’s remarks. The reviewers, experts in a given field from Poland or abroad, are carefully selected by the Editorial Board. Each article is reviewed by two experts, and in the cases of contradicting assessments, a third reviewer is called. The final decision on the acceptance/rejection of the text is taken by the Board of Editors based on the reviewers’ opinions and the author’s comments. If a controversy arises, the Board of Editors may appoint another reviewer. Rejected materials are not returned.
Reviewers evaluate manuscripts based on content without regard to ethnic origin, gender, sexual orientation, citizenship, religious belief or political philosophy of the authors. They must ensure that all the information related to submitted manuscripts is kept as confidential and must report to the Editor-in-Chief if they are aware of copyright infringement and plagiarism on the author's side. They must evaluate the submitted works objectively as well as present their opinions on the works in a clear way in the review form. A reviewer who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the Editor-in-Chief and excuse himself from the review process.
If the member of the editorial board is the author of the article all decisions related to the publication of the text are passed of the other member of the editorial board.

The editors do not charge for the publication of the article. No honoraria are paid to authors and reviewers.
