If you need help with citation, there is a Cite Your Sources link that is also available via the library home page; however, this link is focused on providing help with MLA and APA citation formats.
If you are using something else, e.g., the citation format in the Journal of the American Chemical Society (J. Am.Chem. Soc.), then your best option is to find an article that uses that format and emulate it. The Journal's web site looks as if it has specific citation help, but it doesn't. The tab called "Citation" merely asks you for a volume and page number, assuming that you have a particular citation you want to find.
If you find that you can't formulate your citations properly, please contact Aline or Diana and we will try to help.
