How To Cite References - ACS StyleThe American Chemical Society (ACS) Style is used primarily for publications in chemistry and allied sciences.
Created April 2008 Contents
These guidelines follow the principles given in The ACS Style Guide: Effective Communication of Scientific Information published by the American Chemical Society (ACS), 3rd edition, 2006. This publication constitutes the authoritative international guide to ACS publication standards and style. ACS Style uses a notational method of referencing when referring to a source of information within the text of a document. In its simplest form, a citation is given consisting of a number in superscript format or enclosed by round brackets if the reference is hand written.
Citation Within The TextIndicating the Relevant Reference in the TextA number in superscript format eg. 6, placed in the text of the essay, indicates the relevant reference. The superscript number appears outside the punctuation if the citation applies to a whole sentence or clause. Citations are numbered consecutively in the order in which they appear in the text and each citation corresponds to a numbered reference containing publication information about the source cited in the reference list at the end of the publication, essay or assignment. Once a source has been cited, the same number is used in all subsequent references. No distinction is made between print and electronic references when citing within the text.Here are some examples of this kind of referencing:
It is not necessary to mention either the author(s) or the the date of the reference unless it is relevant
to your text. Citing More Than One Reference at a TimeWhen citing more than one source at a time, the preferred method is to list each reference number separately in ascending order with a comma or dash (without spaces) between each reference:Superscript Format
QuotingUse quotation marks to enclose short direct quotations of up to 50 words:
Use a narrower column width, indented on both sides, for longer quotations of 50 words or more. Do not use quotation marks:
Personal CommunicationsPersonal communications should be included in the text of your document in the same manner as any other source. It is recommended that permission is sought from the source/author of a personal communication if you wish to include quotes in your text. Examples of how to include personal communications in your text:In a conversation with a colleague from the School of Molecular Science34 ... As stated in a letter from B.J. Saul, in July 200235 ...
The Reference List or BibliographyA numbered list of references must be provided at the end of the paper. The list should be arranged in the order of citation in the text of the publication, assignment or essay, not in alphabetical order. List only one reference per reference number. It is very important that you use the correct punctuation and that the order of details in the references is also correct. Capitalisation practice also should be consistent. All titles are given maximal capitalisation. All words other than prepositions, conjunctions, and definite and indefinite articles (a, an, the) are capitalised. Journal abbreviations and book titles are italicised or underlined if references are handwritten. However, if "the" is the first word of the title italicise and capitalise it. The following examples demonstrate the format for a variety of types of references, but this is not exhaustive. Included are some examples of citing electronic documents.
Print DocumentsBooksNote: Given names are not inlcuded only an author's first and middle initial, if known. Capitalise the "v" in Volume for a book title.

Electronic DocumentsNote: When you cite an electronic source try to describe it in the same way you would describe a similar printed publication. If possible, give sufficient information for your readers to retrieve the source themselves.If only the first page number is given, a plus sign indicates following pages, eg. 26+. If page numbers are not given, use paragraph or other section numbers if you need to be specific. An electronic source may not always contain clear author or publisher details. The access information will usually be just the URL of the source. As well as a publication/revision date (if there is one), the date cited is included since an electronic source may change between the time you cite it and the time it is accessed by a reader.
