How to format your references using the Chemical Engineering Progress citation style

This is a short guide how to format citations and the bibliography in a manuscript for Chemical Engineering Progress (CEP). For a complete guide how to prepare your manuscript refer to the journal's instructions to authors.

Using reference management software

Typically you don't format your citations and bibliography by hand. The easiest way is to use a reference manager:

PaperpileThe citation style is built in and you can choose it in Settings > Citation Style or Paperpile > Citation Style in Google Docs.
EndNoteFind the style here: output styles overview
Mendeley, Zotero, Papers, and othersThe style is either built in or you can download a CSL file that is supported by most references management programs.
BibTeXBibTeX syles are usually part of a LaTeX template. Check the instructions to authors if the publisher offers a LaTeX template for this journal.

Journal articles

Those examples are references to articles in scholarly journals and how they are supposed to appear in your bibliography.

Not all journals organize their published articles in volumes and issues, so these fields are optional. Some electronic journals do not provide a page range, but instead list an article identifier. In a case like this it's safe to use the article identifier instead of the page range.

A journal article with 1 author
Knoepfler, P., “My year as a stem-cell blogger,” Nature, 475 (7357), p. 425 (2011).
A journal article with 2 authors
Dubrulle, J., and O. Pourquié, “fgf8 mRNA decay establishes a gradient that couples axial elongation to patterning in the vertebrate embryo,” Nature, 427 (6973), pp. 419–422 (2004).
A journal article with 3 authors
Basu, P., J. Qiu, and K. Powell, “Making a difference,” Nature, 455 (7215), pp. 1002–1003 (2008).
A journal article with 7 or more authors
Lima, M.D., S. Fang, X. Lepró, et al., “Biscrolling nanotube sheets and functional guests into yarns,” Science (New York, N.Y.), 331 (6013), pp. 51–55 (2011).

Books and book chapters

Here are examples of references for authored and edited books as well as book chapters.

An authored book
Singh, M.P., and M.N. Huhns, “Service-Oriented Computing,” John Wiley & Sons, Ltd, Chichester, UK (2006).
An edited book
González, R.G., J.A. Hirsch, M.H. Lev, P.W. Schaefer, and L.H. Schwamm, eds., “Acute Ischemic Stroke: Imaging and Intervention,” 2nd ed., Springer, Berlin, Heidelberg (2011).
A chapter in an edited book
Hazewinkel, M., N. Gubareni, and V.V. Kirichenko, “Frobenius algebras and quasi-Frobenius rings,” in M. Hazewinkel, N. Gubareni and V. V. Kirichenko, eds., , “Algebras, Rings and Modules,” Springer Netherlands, Dordrecht, pp. 161–217 (2007).

Web sites

Sometimes references to web sites should appear directly in the text rather than in the bibliography. Refer to the Instructions to authors for Chemical Engineering Progress.

Blog post
Andrew, E., “Meet The World’s Most-Traded, Least-Known Mammal,” IFLScience, 2015.


This example shows the general structure used for government reports, technical reports, and scientific reports. If you can't locate the report number then it might be better to cite the report as a book. For reports it is usually not individual people that are credited as authors, but a governmental department or agency like "U. S. Food and Drug Administration" or "National Cancer Institute".

Government report
Government Accountability Office, “Information Security: Weak Controls Place DC Highway Trust Fund and Other Data at Risk,” U.S. Government Printing Office, Washington, DC (2001).

Theses and dissertations

Theses including Ph.D. dissertations, Master's theses or Bachelor theses follow the basic format outlined below.

Doctoral dissertation
Etchberger, J.F., “The cis-regulatory logic of gustatory neuron development in Caenorhabditis elegans,” 2008.

News paper articles

Unlike scholarly journals, news papers do not usually have a volume and issue number. Instead, the full date and page number is required for a correct reference.

New York Times article
Koblin, J., “Nielsen Tackles a Mystery: Netflix Ratings,” New York Times, 2017, B2.

In-text citations

References should be cited in the text by sequential numbers in square brackets:

This sentence cites one reference [2].
This sentence cites two references [3, 4].
This sentence cites four references [4, 5, 6, 8].
