ACS citation questions

What does an ACS journal citation look like?

Watson, J. D.; Crick, F. H. C. Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid. Nature 1953, 171 (4356), 737–738. DOI: 10.1038/171737a0 — with Nature in italics, 1953 in bold and 171 in italics.

Does ACS use et al.?

In the reference list ACS recommends listing every author. Some journals cap the list at ten authors followed by “et al.” In the text you can write “Novoselov et al. showed…”

Where do I find ACS journal abbreviations?

Use CAS Source Index (CASSI). Common ones: J. Am. Chem. Soc., Angew. Chem., Int. Ed., Chem. Rev., J. Phys. Chem. A.

Is the issue number required in ACS?

It is optional; include it consistently if you use it. ScholarCite includes it when you fill the field.
