Citing Right

Chemical engineers traditionally use the citation style followed for publications of the American Chemical Society (ACS) or that followed by American Institute of Chemical Engineers (AIChE).

Detailed information on the ACS style can be found at ACS Author Guide.

Detailed information on the AIChE style can be found in their Style Guide for Chemical Engineering Progress (CEP)

More Citation Assistance

Most databases provided by the libraries have a "Cite" feature built in. Look for a link or button for citing. If the link is available, you will see a screen which provides a citation in your preferred format that you can cut and paste into your bibliography.

Many electronic resources offer citation creators and there are some that are freely available on the web. Feel free to use the links below at your convenience.

However, make sure you carefully edit the results before you paste them into your bibliography, citation creators are not always perfect. Automatic citation generation is only as good as the details made available from the database.

What Is Common Knowledge?

"Common knowledge" -- you don't need to cite where you found "common knowledge". But what is "common knowledge"? Guess what -- it varies. Here is a safe definition, because you don't want to be accused of plagiarism.

Did you know it without looking it up?  If you are just learning about your field, you should err on the side of caution. Better to cite something that didn't need a citation, then to be accused of plagiarism.

Would other people in the class know this?  Common knowledge is based, to some extent, on what the "general practitioner" in the field would know. And what would be general knowledge for a practicing electrical engineer MAY NOT be common knowledge for a freshman engineering student.

Do you find the information in many PUBLISHED (not web pages) resources? Some experts say if you find it in 3 reference tools, no need to cite. Others say 5. If you don't have time to check that the information has been used in many different places, cite it. Play it safe. The citation can be easily removed later and until the paper is in it's final version, you will know where to go back and verify the information.

  • Example 1:  Water boils at 100 °C. (I looked it up to make sure I was right. Still it is common knowledge and I will not cite my source.)
  • Example 2:  The melting point of acacetin is 263 °C. (For an organic chemist, this might be common knowledge. For me it is not. I would cite it for two reasons. First, I had to go find it. Second, I want to show the reader it is valid number.)
  • Example 3: Nixon resigned from the US Presidency. (Common knowledge)
  • Example 4: Nixon resigned from the US Presidency at the urging of ....... (Not so common knowledge, I would cite where I found that information.)
