When an author's name contains something like "van der", "de la", etc, and you wish to initial the author's first/middle names (all but surname) in a reference, how do you deal with the extra words?
For example, if I wish to reference a paper by António Franco de Oliveira Falcão, would I write FalcãoFalcão, A.F.O. or Falcão, A.F.d.O., A.F.O.or maybe Falcão, A.F.D.O.? FalcãoAlthough, A.F.d.O.? Falcãoit seems that this is a Portuguese name, A.F.D.Owith two surnames.? I'm not sure how I should deal with two surnames
Edit: I'm using the Leeds Numeric style. I've found an example of an author with the name Leo Cornelius van Rijn, which is referenced as van Rijn, L.C.van Rijn, L.C., so that answers what to do if the word is part of the surname. But in the Falcão example "de" is part of the Oliveira name, I'm not sure if that would be part of the surname or not.
Edit 2: It seems that this is a Portuguese name, with two surnames. I'm not sure how I should deal with two surnames
