I am currently using the built in citation style 'Journal of the Air & Waste Management Association' as it is the closest to the style that I need. However, the one issue I am having is when it comes to documents with the same first author and year, but different subsequent authors, shown below:
I have a paper by (Elphick, Davies, et al. 2011) and (Elphick, Bergh, et
al. 2011).
What I want is a paper by (Elphick et al. 2011a) and (Elphick et al.
2011b).
I have a very rudimentary knowledge of computer programming, and have been able to work out some small issues I was having using the CSL editor. However, I have not been able to figure out how to resolve this issue. Is anyone able to help me with this? Thanks!
