Reference citation numbers formatting

Like in-text citations, the formatting of references requires great care. The appropriate use of punctuation, fonts, parentheses, in addition to the inclusion, exclusion, and sequencing of information (e.g., authors, title of article, title of journal, year of publication, page numbers), reveals your attention to detail, expected of good writers and by expert and scientific readers. 

A References section is needed if you cite others works in your poster, unless you inserted an abbreviated reference directly into the text. If you include citations in only one section of your poster (e.g., the Introduction), the References section can be placed at the end of that section otherwise, include the references at the end or bottom of your poster. Format the references with the citation format used in the poster number them in citation order (if you used numerical citations) or arrange them alphabetically (if you used author—date citations). Because of space limitations, references may be abbreviated. Consider the following examples for a poster with numerical citations ... 

Beginning writers sometimes incorrectly combine numerical and alphabetical reference formats. Consider the example below. The in-text citations are not numbered sequentially (i.e., 1, 2,3,...), and the literature cited is in alphabetical order rather than in citation order. 

Are citations and references formatted in a parallel fashion Have you used only one citation format throughout (superscript numbers, italic numbers in parentheses, or author-date format) ... 

Papers are cited via a superscript or bracketed reference number inserted at the appropriate point. Normal format would be, for example computational chemistry has shown that. .. or Jones [55,82] has claimed that. .. . Repeated citations use the number from the first citation. In the true numerical method (e.g. as in Nature, Science), numbers are allocated by order of citation in the text. This is by far the most common approach in chemistry journals. Note that adding or removing references is tedious, so the numbering should be done only when the text is finalized. 

References to citations in the tabulated summaries are to be included throughout the text and are to be in the following format (Table X.X, Study/report number). 

There are two ways this section can be presented. If you put it at this location in the report, it should contain only references cited in the sections of the report preceding this section. References may be listed by number and cited in the text by this number, either as a superscript or as a number in parentheses or in brackets (preferred). Another method is to cite the reference by the author and year. You should consult the end of a chapter or the end of the book in any of your chemical engineering texts for the correct citation format. If you choose this method, then any references to data sources appearing in the Appendix should appear on the page on which that calculation is presented.
