Liberation: Referencing

 

Advanced Tutorial: Referencing Multiple Authors

Three or more authors

If there are more than two authors then your citation should give the name of the first author followed by the abbreviation et al. (meaning 'and others').

For example, you may write:

De Meer et al. (2004) concluded that having had a cat in childhood protects against adult asthma.

In your reference list you should normally include all the authors:

De Meer, G., Toelle, B., Ng, K., Tovey, E. and Marks, G. (2004) Presence and timing of cat ownership by age 18 and the effect on atopy and asthma at age 28. Journal of allergy and clinical immunology. 113 (3), 433-438.

But if there are more than three authors it is acceptable to abbreviate using et al. as follows:

De Meer, G. et al. (2004) Presence and timing of cat ownership by age 18 and the effect on atopy and asthma at age 28. Journal of allergy and clinical immunology. 113 (3), 433-438.
