What is a requirement for reuse of published material according to ethical guidelines?

In the context of ethical guidelines for the reuse of published material, obtaining permission before reuse is a fundamental requirement. This ensures that the rights of the original authors and publishers are respected, upholding the integrity of the publication process and the value of intellectual property.

When permission is sought, it generally involves engaging with copyright holders or publishers to obtain the necessary permissions for reuse, whether for full articles, excerpts, or any other material. This practice not only complies with legal standards but also aligns with ethical considerations surrounding respect for the contributions of other researchers and their work.

Other options imply scenarios where permission may not be necessary, which could lead to unauthorized use of copyrighted material. This underlines the importance of always obtaining permission as a best practice in the realm of academic publishing and research.
