How to include biblatex \nocite authors in authors index

Question

Occasionally using biblatex I want to reference an authored work (i) without including a formal citation in the text, while (ii) including the work in the bibliography, and (iii) including all of the work's authors in the citations [author] index, each of these entries back-referring to the page in which the non-citation reference is included.

I can achieve (i) and (ii) using \nocite in the standard way. However, \nocite doesn't accomplish (iii). At the moment, I am manually entering possibly multiple \index[author]{...} commands with each \nocite where I want this behavior to appear, but find this tedious and error prone, especially when non-cited works include large numbers of authors.

Any ideas how I can configure \nocite or another suitable command to include option for behaving in the standard way while also including each of the work's authors in the citations index?

Answer 1

You can define a new "cite" command that only starts the indexing routine

\DeclareCiteCommand{\nociteindex}
  {}
  {\usebibmacro{citeindex}}
  {}
  {}

It will print nothing, but it will send the work to the bibliography and index. This solution also indexes the title, if you only want the name, go with

\DeclareCiteCommand{\nociteindex}
  {}
  {\indexnames{labelname}}
  {}
  {}
