Biblatex: Suppress shorthand in a selection of documents

Question

My problem is this: I use one biblatex-file as a source for a number of documents. In the biblatex-file I used shorthand in every entry. The problem is that in some documents I need to cite the references fully rather than the short form. My question: Is there something a command that I could add to my preamble in order to suppress the shorthand entry and to get full title output?

Answer 1

If you simply want to suppress the use of shorthands in citation commands for all entries, adding

\AtEveryCitekey{\clearfield{shorthand}}

to the preamble should do. If you have more specific requirements, please add a MWE to your question.

Answer 2

To completely clear the shorthand field use

\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map{
      \step[fieldset=shorthand, null]
    }
  }
}

This also works for numeric styles, where the shorthand is used instead of numeric labels, and enables proper disambiguation for authoryear styles.

Answer 3

If the problem is to remove display of shorthands in the reference list, use:

\AtEveryBibitem{\clearfield{shorthand}} 

(I don't quite get the question as to whether shorthands are to be removed from citation keys or from reference list. Combining it with Lockstep's answer this is useful.)
