No matter how many authors you have in a paper, we only need to fill in the first author when checking the duplicate. For example, our common HowNet duplicate checking system only identifies the first author of the paper. What if your paper is published by several people and everyone needs a duplicate check report?

This will definitely happen, but only the first author can be filled in, and other authors will not delete the papers published by the first author before, and some contents of the papers may be mistaken for plagiarism by the duplicate checking system.

First author. If your paper was published by several people before, you need to review the report now, and you can only fill in the first author. After the second author, the system may find plagiarism. The steps of submitting free papers for duplicate checking are simple, but if you don't understand the rules of duplicate checking for free papers, blindly submitting papers for duplicate checking may cause losses.
