The NLM style requires that items be cited either parenthetically or with superscript numbers for attribution. The systems are:

  • Author-Year system
    • Example at end of sentence: (Johnson 2011)
    • Example in text: Johnson et al. (2011) found that the lack of copyright information available provided a direct correlation to the comfort of faculty members interpreting copyright law.
  • Sequence system
    • […] last day¹.
    • This system means that the reference list is in the order that references appear in the paper
  • Author-sequence system
    • […] last day¹.
    • This system means that author names are ordered alphabetically in the reference list, regardless of when they appeared in the text.

If you’re using EndNote, keep in mind it’s not an “import it and forget it” tool. You have some things to verify before signing off on the citations, since it only knows what you tell it (or what the database tells it). Check the following before finalizing a paper:

1)         Reference type. Make sure each reference in EndNote says “journal article” or whatever it is you’re citing. Sometimes it may come through as a generic reference, or even serial, and the citation will be incorrect. Fixing your reference type will hopefully account for most issues. 

Sample journal citation:

Ulbrich TR, Dula CAC, Green CG, Porter K, Bennett MS. Factors influencing community pharmacists' enrollment in a state prescription monitoring program. J Am Pharm Assoc. 2010;50(5):588-94.

2)         # of authors included. If over six authors, leave the first 3 in the record and say “et al” afterwards.

3)         Year of publication is after the journal abbreviation. 

4)         Your journal title is abbreviated. Search PubMed for the journal title to determine what the abbreviation is. 

Check your results with a standard NLM style citation to ensure the material is all there and correctly formatted. Especially watch for article title translation. Items which should be capitalized are often not (acronyms, program names, etc.)

A special note about web page citations.

Web page citations are notoriously tricky in EndNote. You need to include in your reference:

  • the last updated date (if available)
  • the date cited
  • format [Internet]
  • the name of the official web site
  • title of the page you're citing
  • copyright dates
  • Number of screens is the number of times you can press the page down key before you get to the bottom of the page.
  • URL of the page
