as I did a search regarding this topic, I came accros the post “Consecutive Citations by the Same Author - one bracket too much” ofphinchen in 1/12/2010 saying that indeed for citations by the same author in two different years the following problem arises: Smith (1999, (2001).
I have the problem that it doesn’t at all omit the repeated author. For instance these two articles:
Mette, M.F., van der Winden, J., Matzke, M.A., and Matzke, A.J. (1999)
Mette, M.F., Aufsatz, W., van der Winden, J., Matzke, M.A., and Matzke, A.J. (2000)
the intext citation is: Mette et al., 1999; Mette et al., 2000
Yes, I can never get that citation to work unless all the authors are exactly the same, which makes no real sense to me. I just use the edit citation> exclude author for the second one, to get what I am looking for (and I don’t worry about the semi-colon vs comma difference, if you do, then you need to hide both the author and the year and type in the comma-space-year for the second citation).
