Under what condition is reusing previously published material acceptable?

Reusing previously published material is acceptable when permission is obtained and relevant parties are informed because this aligns with ethical research practices and legal guidelines regarding copyright. Obtaining permission ensures that the original authors and publishers retain control over their work and allows for the reuse of content without infringing on intellectual property rights. Moreover, informing all relevant parties maintains transparency and accountability in the research process, fostering trust and collaboration in the academic community.

In contrast, simply believing that reused material adds value may not be sufficient justification for duplication, as it may overlook the legal and ethical considerations involved. Using a small excerpt might be permissible under the doctrine of fair use, but it does not automatically clear the requirement for permission in all cases. Additionally, reusing material to support a different context, while potentially beneficial, does not replace the necessity of obtaining permission and ensuring proper acknowledgment of the original source.
