By default, when you choose style=alphabetic with biblatex, citations will take the form [Abc12]. I would like to have only the letters – e.g. [Abc] – unless there is an ambiguity, in which case it should be numbered, e.g. [Abc1], [Abc2], etc.

  • Yes, thanks, that's the answer. I suggest marking my question as a duplicate (instead of deleting it), so that others find their way more easily to the solution. – Deniz May 3 at 14:37
