Even if you are confident in the value and originality of your research and writing, those efforts will be wasted if you do not make proper citations where credit is due. The citation format should not be overlooked as a surface-level stylistic issue, but carefully reviewed as a critical component of your writing. Be sure to check the citation format required by the publisher in advance - English-language publishers may not deny publication of your work based on improper citations, but it is a major red flag on the quality of your research, and may add extra time and challenges to publication.
