ACS - Referencing Guide

Internet Documents

Information

Cite documents published on the internet according to the specific guidelines for the type of document. More specific information is available for Books and Journal Articles.

Government reports and company annual reports are examples of documents that may be published on the internet.

When including government entities in a citation, whether as the authoring organization or the publisher, begin with the highest level agency or department, then the next level organization, and so on to convey the hierarchy. There may be several components to record.

Include the DOI in the citation if there is one (no access date needed),or include the URL and access date.

Wikipedia is included although it is not generally recommended to cite it as a source. The access date is essential, so the correct historical entry can be found, if necessary, via the "View History" tab on the article page.

The date given can be the date when that specific page or file was published, posted, deposited, edited, revised, or last reviewed. Sometimes, the date on the page has nothing to do with the content itself but rather refers to a global update to the website, like a change in copyright year. In cases like these, or if there is no date at all, use “n.d.” for “no date.”

Please note: If no author or editor is given and the document is not a part, article or chapter, then citation is by title.
