New .bib-field fullauthor to be used instead of author

Question

In an extremely long bibliography it can be quite annoying to have the same author with a somewhat different name in each entry, especially if the publications appear as a list under the name of the author. On the other hand we need the correct data as they appear on the publications.

So I want an optional field, let's call it fullauthor, where I simply add up all information from the single entries. For my working bibliography I want to be able to set fullauthor = true as option to biblatex, else I will do nothing, in which case the fullauthor-field is just ignored.

Answer 1

I suggest you use a Sourcemapping. Give fullauthor for the full name in the bibliography and fullciteauthor for the name in citations. Then

\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map[overwrite=true]{
      \step[fieldsource=fullauthor, final]
      \step[fieldset=author, origfieldval]
      \step[fieldsource=fullciteauthor, final]
      \step[fieldset=shortauthor, origfieldval]
    }
  }
}

together with

@Article{Dude:White,
  author         = {{The Dude}},
  gender         = {sm},
  fullauthor     = {Lebowski \mkbibbrackets{Slakyech}, \RN{2}
                    \mkbibparens{\mkbibquote{The Dude}},
                    Jeff\mkbibbrackets{rey} \mkbibbrackets{Robert}},
  fullciteauthor = {Jeff Lebowski},                   
  title          = {Making White Russian Even Better},
  journaltitle   = {Slackers Quarterly},
  year           = 1973,
  volume         = 3,
  number         = 2,
  pages          = {7-32}
}

gives you what you want.

It would be much more complicated to make fullauthor a replacement of author in the biblatex level.
