# Citation with ACS style and superscript

I'm using biblatex and biber to generate my bibliography:

\usepackage[backend=biber,style=chem-acs]{biblatex}


but it doesn't look like proposed here: http://ctan.math.utah.edu/ctan/tex-archive/macros/latex/contrib/biblatex-contrib/biblatex-chem/biblatex-chem-acs.pdf

It rather looks like shown here: https://de.sharelatex.com/learn/Biblatex_bibliography_styles

As I understood the style is set automatically. Does that mean it is the new standard ACS style or am I doing something wrong?

Thank you

Thank you for the prompt answers and sorry for being unprecise. For the first link how I expected it so see it with the superscript and reference listing is as follows:

The second link provides how I have it in my thesis

• The link you give to how it looks is not really helpful: that's a listing of all the standard styles. Can you edit in a picture of what you are seeing? – Joseph Wright Sep 6 '18 at 6:31
• Interestingly biblatex-chem-acs.tex explicitly sets \usepackage[style=chem-acs,biblabel=dot]{biblatex} so it is not too surprising that the default output and the documentation differ. For superscript citations you should use \autocite, \cite still gives normal numbers. – moewe Sep 6 '18 at 6:43
• @JosephWright ^^^^ I can't access JACS papers at the moment, my university's authentication system does not load, but I could find a few papers on the web and all of them have parentheses around the numbers in the bibliography, so the biblabel=dot in the call to biblatex in biblatex-chem-acs.tex should probably be removed: It only causes confusion. – moewe Sep 6 '18 at 7:22
• @moewe The exact style depends on the journal: the ACS have over 30, each with it's own settings! This is one of the places they vary. – Joseph Wright Sep 6 '18 at 7:29
• @moewe Ah, right: I'm not sure why I have that anyway. For the next relaese! – Joseph Wright Sep 6 '18 at 7:40

biblatex-chem does not modify the behaviour of \cite, it still gives a normal citation number (this is in line with what most other styles do as well). Ideally you should use \autocite to get citations as desired by the style, in case of chem-acs you then get superscript citations as desired. \autocite is at a higher level of abstraction because its behaviour can be changed with a simple option.

As mentioned in the comments the round parentheses you see in the bibliography are in compliance with the style required for the J. Am. Chem. Soc. The ACS also has some journals with a slightly different style that requires a dots after the numbers. The option biblabel can be used to control the format of the label number in the bibliography. The default settings of chem-acs give you the parentheses, but earlier versions of the style documentation biblatex-chem-acs.pdf would load chem-acs with the option biblabel=dot (from version 1.1v 2018-09-06 onward, biblatex-chem's style documentations use the normal settings of their respective style).

The following MWE shows chem-acs with the settings for the J. Am. Chem. Soc.
