Citing e-journals still follow the conventions used for citing print journals. You must include all of the components below:
Note: the DOI is becoming the accepted norm for e-journal citations - use it where you have consulted an e-journal version rather than the URL of the journal, which will vary depending on the source of access. As per the norm if you use the DOI, you do not have to state from where you obtained the Internet copy of the journal article (Available: ...), nor do you have to give the date of access, because the DOI is stable and perpetual, unlike the URL. Depending on your supervisor's preference you may include the date the reference was accessed.
If you can not find a DOI, an example of how to cite with a URL is also provided below.
Journal article titles are written in lower case - use upper case letters only where necessary, eg. in places or personal names, or as in H5N1.
A DOI is a unique ID number that publishers are using increasingly to identify electronic articles (as opposed to e-journals which have an ISSN [International Standard Serial Number]). So the DOI identifies the unique article; the ISSN identifies the unique journal.
Examples of an e-journal citations with a DOI:
1. Strachan, M.W., Price, J.F. & Frier, B.M. 2008. Diabetes, cognitive impairment, and dementia. BMJ 336(7634):6. doi: 10.1136/bmj.39386.664016.BE [Accessed 10.01.11]
2. Strachan, M.W., Price, J.F. & Frier, B.M. 2008. Diabetes, cognitive impairment, and dementia. BMJ336 (7634):6. doi: 10.1136/bmj.39386.664016.BE
Note: If there is a DOI, you do not need to give the URL. If there is no DOI, the URL must be given.
Important: Even if you use a DOI, you still have to cite the entire reference plus the DOI.
A DOI will never change - it is a permanent link to an electronic article or document.
To find a document using a DOI:
This will allow the reader to click through directly to your source from your list of references.
You will notice from these examples that using a DOI is neater than using a URL in an e-journal citation. You should therefore always try to use the DOI whenever possible.
