Self-citation is the practice of referencing previously published work. It is critical to provide citations whenever concepts, details, or other material has been covered in previous publications.
Self-citation in abundance may be called crass and unprofessional, and in certain circumstances, immoral. In either situation, self-citation (even unnecessary self-citation) can be appropriate and forgivable in certain circumstances. For instance, if you work in a specialized area of science, self-citation can be required.
Is there any software tool to automatically detect self-citations?
