What must an author do before reusing their previously published material?

An author must inform all relevant parties and obtain permission before reusing their previously published material to ensure compliance with copyright laws and publisher policies. This step is crucial because the original work may still be under copyright protection, and reusing it without obtaining the necessary permissions could lead to legal issues or breaches of ethical guidelines. Publishers often have specific rules regarding the reuse of published content, and authors are obligated to adhere to these rules to respect the intellectual property rights associated with their work.

In addition, obtaining permission may involve engaging with co-authors, funding agencies, or institutions that may hold rights to the work. This collaborative aspect underscores the importance of maintaining transparency and fostering good practices within the academic and research community.
