Guide to Numerical Citations: ACS, AMA, IEEE, NLM, and Vancouver

Academic and professional writing fundamentally provides the base for citations. To prevent intellectual property violations and trace information sources, they allow originators of reference works to be given recognition through these referencing formats. Properly cited material maintains both the author’s credibility as well as the paper’s reliability.


Introduction to Numerical Citations

Numerical citation is one such referencing style that uses numbers that appear as superscripts or inside square/round brackets. These correspond to references listed in numerical order at the end of a document. This approach is commonly employed in scientific, technical, and medical papers because it is straightforward and efficient.

ACS (American Chemical Society): The ACS style is used in chemistry and related fields, employing a numerical system for in-text citations and a sequentially numbered reference list.

AMA (American Medical Association): The AMA style is widely accepted in the medical and scientific fields, using numbered lists of references and in-text superscript numbers.

IEEE (Institute of Electrical and Electronics Engineers): Engineering disciplines often apply the IEEE style. It also uses bracketed numbers for citing texts and then uses corresponding numeric reference lists.

NLM (National Library of Medicine): The NLM style mainly concerns biomedical sciences where it employs a numerical citation system; thus, the bibliography is arranged according to how they are cited in the text.

Vancouver: The Vancouver style is known for its use by most authors in medical and scientific literature; citations appear as numbers on a page while references remain ordered numerically according to their sequence of appearance.

Manual Citations vs. Citation Machine

Creating citations manually can be a time-consuming and meticulous process. It involves understanding the specific formatting rules of each citation style and ensuring every detail is correct. This can be particularly challenging when dealing with numerous sources.
