Life and Health Sciences Harvard Referencing Guidelines

Several works by the same author/s in the same year

If you are referencing several works published by the same author or authors in the same year, they should be differentiated by adding a lower case letter (a,b,c, etc.) with no space, after the year and in brackets. 

If several works published by the same author or authors in the same year are referred to on a single occasion they can all be referred to by using lower case letters.
