Autoplagiarism refers to the act of using one's own previously published work in a new publication without proper citation or acknowledgement. There are several alternative terms for this practice. One synonym is self-plagiarism, which is used to describe an author's reuse of their own work in a new context. Another common synonym is duplicate publication, which is the act of publishing the same work in multiple venues without disclosure. Other terms include redundant publication, text recycling, and double dipping. All of these phrases refer to the same fundamental act of reusing one's own work in a way that is not ethical or transparent.
