Hi! I was wondering what to do in this situation. I have 2 references like so: Beausaert, S., Segers, M., & Gijselaers, W. (2011) Beausaert, S., Segers, M., Van der Rijt, J., & Gijselaers, W. (2011) Now when I cite them (after the first time) in text it's Beauseart et al. (2011) and Beauseart et al. (2011). How can the reader or me distiguish them? Should I add an a or b after the year. Or is that only when all the authors are the same? I use Mendeley and it automatically cites it to: (Beauseart et al., 2011) (Beausaert, Segers, Van der Rijt, et al., 2011)
