- If available, use the DOI for online journals.
- If no DOI use the home page URL for the journal rather than the database name. The manual advises that this may necessitate a "quick web search to locate this URL."
- Retrieval dates are no longer necessary for websites unless the material may change over time (e.g. Wikis).
- When working on the References list at the end of your paper, if there are eight or more authors listed for any resource, include the first six authors' names, then insert three dots and add the last author's name. The following is an example:
Yoon, P. W., Chen, B., Faucett, A., Clyne, M., Gwinn, M., Lubin, I. M., . . .
Muin, J. (2001) Public health impact of genetic tests at the end of the
20th century. Genetics in Medicine, 3, 405-410.
