Many journals and professional society publishers specify their own citation styles, which will vary in some aspects from more widely-used citation styles. Examine the reference section of articles from a particular journal for examples of formatting, but be aware that editors may not always catch author errors prior to publication. For specifics, locate a journal or publisher website and look for a link to "authors," "instructions for authors," "author guidelines," "manuscript submission," "submission guidelines," or similar information. For example, here is the guide for authors and manuscript requirements for ASCE Journals (published by the American Society of Civil Engineers).
