Modifying bibliography with biblatex/biber (apa-style) location+publisher+doi

Question

Concerning the citation and bibliography of my thesis, some issues I could solve myself, with others I got help. But here is where I'm stuck:

If there is a book or bookchapter that's got a doi, location+publisher won't show up (for example check Backhaus et al.; Castells; Revelle/Condon), but without doi, location+publisher show up (for example check Foucault. Is there a possibility to change that? It should look like: »location: publisher. doi:12345« (for example »Oxford: Wiley-Blackwell. doi:10.1002/9781444319514«).

Maybe you also notice, that in the case of Castells the volume number is not shown, too, whereas for Revelle/Condon without doi it is shown, but in the arabic number, not the roman number (even if that's the information of the bibentry). In the case of Foucault the volume number is not shown although there's no doi. Could that be fixed, too?

Maybe this has got to do with changes to an APA feature? Or does it have to do with the zotero-import of my bibentries? See, before this problem happened, all books would be imported as »@book« (Backhaus et al.), whereas now it's »@mvbook« (Foucault).

I'm using APA-Style with biber as backend for biblatex. All help is much appreciated.

Answer 1

I have said this before, but for the benefit of other readers: It is usually a bad idea to try to modify specialised styles like biblatex-apa and biblatex-chicago so heavily. These styles were specifically written to conform to very strict (and sometimes complicated and slightly inconsistent) rules of an authoritative style guide. That means that the code is much more complicated than the standard styles, which were meant to be modified as needed. For future project I strongly advise to build your customised style upon one of the standard styles (probably authoryear in this case) \begin{advertising} or upon one of the style of my biblatex-ext family \end{advertising}

It is a feature of APA style that location and publisher are dropped if the DOI is present for chapters like @incollection or @inbook. That can be turned off by redefining the macro location+publisher.

The volume field in Castells_2010 and Foucault_2004 is not shown because the entries lack a maintitle field. Usually the maintitle+volume are used together like

@book{Castells_2010,
  langid       = {english},
  location     = {Oxford},
  maintitle    = {The Information Age},
  mainsubtitle = {Economy, Society, and Culture},
  title        = {The Rise of the Network Society},
  volume       = {I},
  edition      = {2. Aufl.},
  isbn         = {978-1-4443-1951-4},
  volumes      = {III},
  publisher    = {Wiley-Blackwell},
  date         = {2010},
  author       = {Castells, Manuel},
  doi          = {10.1002/9781444319514}
}
@book{Foucault_2004,
  langid     = {ngerman},
  location   = {Frankfurt am Main},
  maintitle  = {Geschichte der Gouvernmentalit{\"a}t},
  volume     = {II},
  title      = {Die Geburt der Biopolitik},
  subtitle   = {Vorlesung am Coll{\`e}ge de France 1978\textendash{}1979},
  isbn       = {978-3-518-58393-7},
  shorttitle = {Die Geburt der Biopolitik},
  volumes    = {II},
  pagetotal  = {517},
  series     = {Taschenbuch Wissenschaft},
  publisher  = {Suhrkamp},
  date       = {2004},
  author     = {Foucault, Michel},
  editor     = {Sennelart, Michel},
  translator = {Brede-Konersmann, Claudia and Schr{\"o}der, J{\"u}rgen}
}

(note that I also split up fields into ...title and ...subtitle where appropriate).

Since both entries refer only to one (pyhsical) book of a a multi-volume project, @book is the appropriate entry type. I would use @mvbook only if I wanted to refer to the entire multi-volume work at once for example

@mvbook{knuth:ct,
  author       = {Knuth, Donald E.},
  title        = {Computers \& Typesetting},
  date         = {1984/1986},
  volumes      = 5,
  publisher    = {Addison-Wesley},
  location     = {Reading, Mass.},
}

Similarly volumes (in plural) only makes sense if a work consists of several volumes, and that will always be a @mvbook/@mvcollection. Your entries, however, refer to just one book and so volumes is not really needed (except as an volume 2 of 3 sort of thing, which I don't think any style does).

The two code-level changes have been marked with today's date 2018-09-24 so they are easier to spot.
