[Tex/LaTex] How to suppress source type in apacite (APA) reference list without removing the type-field entry

apa-style

I am using apacite for APA references in my thesis. It works beautifully with the exception that is displays the source type brackets in the reference list, which I don't want (see below).
enter image description here
Leaving the type field blank is not an option because I manage my bibliography in EndNote and then export it, which automatically fills this field in.

Below is a minimum working example.

\documentclass{article}
\usepackage[natbibapa]{apacite}

\begin{document}
\nocite{*}
\bibliography{sources.bib}
\bibliographystyle{apacite}

\end{document}

My .bib file is rather inconspicuous, but I am including it for completeness.

@article{mandelbrot1963variation,
author = {Mandelbrot, Benoît},
title = {The variation of certain speculative prices},
journal = {The Journal of Business},
volume = {36},
number = {4},
pages = {394-419},
year = {1963},
type = {Journal Article}
}

Suggestions are greatly appreciated!

OPTION #1: using a modified `.bst` file

First of all, from the command line, run

kpsewhich apacite.bst

to know where the file apacite.bst is. Its path should be TEXMF/bibtex/bst/apacite/.

Now copy apacite.bst in the directory where your .tex file is, and rename it to myapacite.bst.

Then open myapacite.bst in your editor, search for the lines

FUNCTION {format.atitle.type.check}
{ format.aetitle.check
  format.atype.check   connect.with.space.check
  title format.atitle.connect
}

and replace them with

FUNCTION {format.atitle.type.check}
{ format.aetitle.check
  title format.atitle.connect
}

Then search for the lines

FUNCTION {format.atitle.type.trans.check}
{ format.aetitle.check
  format.atype.check   connect.with.space.check
  format.atrans.check  connect.with.space.check
  title format.atitle.connect
}

and replace them with

FUNCTION {format.atitle.type.trans.check}
{ format.aetitle.check
  format.atrans.check  connect.with.space.check
  title format.atitle.connect
}

Save the file.

Now in your document, replace

\bibliographystyle{apacite}

with

\bibliographystyle{myapacite}

and you're done.

MWE

\begin{filecontents*}{sources.bib}
@article{mandelbrot1963variation,
author = {Mandelbrot, Benoît},
title = {The variation of certain speculative prices},
journal = {The Journal of Business},
volume = {36},
number = {4},
pages = {394-419},
year = {1963},
type = {Journal Article}
}
\end{filecontents*}

\documentclass{article}
\usepackage[natbibapa]{apacite}

\begin{document}
\nocite{*}
\bibliography{sources}
\bibliographystyle{myapacite}

\end{document}

Output:

enter image description here

Note that you have

\bibliography{sources.bib}

in your MWE, but it should be

\bibliography{sources}

unless your .bib file is named sources.bib.bib....

OPTION #2: using `biblatex-apa`

Using biblatex with the apa style, the type field isn't printed by default.

Here's your MWE modified for using biblatex:

\begin{filecontents*}{sources.bib}
@article{mandelbrot1963variation,
author = {Mandelbrot, Benoît},
title = {The variation of certain speculative prices},
journal = {The Journal of Business},
volume = {36},
number = {4},
pages = {394-419},
year = {1963},
type = {Journal Article}
}
\end{filecontents*}

\documentclass{article}
\usepackage[american]{babel}
\usepackage[utf8]{inputenc}
\usepackage{csquotes}
\usepackage[%
    style=apa,
    natbib=true,
    firstinits=true,
    uniquename=init,
    backend=biber]{biblatex}
\DeclareLanguageMapping{american}{american-apa}

\addbibresource{sources.bib}

\begin{document}
\nocite{*}

\printbibliography

\end{document}

[Tex/LaTex] How to sometimes suppress the printing of the URL field

This is also quite easy to do. I'm assuming that the doi and url fields trump the publisher and location field, so the way to implement this is to only print these fields if the doi and url fields are undefined. So we add the following:

\renewbibmacro*{location+publisher}{%
  \iffieldundef{doi}{
     \iffieldundef{url}{
         \printlist{location}%
         \setunit*{\addcolon\space}%
         \printlist{publisher}%
         \newunit}{}}{}
  }

I must say that I find this an odd rule on the APA's part: publisher and location are usually only printed with books, and in my opinion the publisher is an important piece of information that has very little to do with "source" information, and more to do with e.g. providing information about the reliability of the source. If a book is published by a major university press that fact tells me a lot compared to if the publisher is "Joe's Spiralbound Book Barn". Somehow just having a doi doesn't help with that.

Here's a sample document with three bib entries with different amounts of source information included.

\documentclass[endnotes]{apa6e}
\usepackage[american]{babel}
\usepackage{csquotes} 
\usepackage[style=apa]{biblatex} 
\DeclareLanguageMapping{american}{american-apa}

\abstract{An abstract}

\begin{filecontents}{\jobname.bib}

    Address = {Dordrecht},
    Author = {Noam Chomsky},
    Booktitle = {Lectures on Government and Binding},
    Publisher = {Foris Publications},
    Title = {Lectures on Government and Binding},
    Url = {http://url.url.url},
    Year = {1981}}

@book{Chomsky1986,
    Address = {Cambridge, MA},
    Author = {Chomsky, Noam},
    Booktitle = {Barriers},
    Doi = {http://doi.doi.doi},
    Publisher = {{MIT} Press},
    Title = {Barriers},
    Url = {http://url.url.url},
    Year = {1986}}

    Publisher = {{MIT} Press},
    Title = {Some Concepts and Consequences of the Theory of Government and Binding},
    Year = {1982}}

\end{filecontents}
\addbibresource{\jobname.bib}

  }

[Tex/LaTex] German APA reference: origyear field is incomplete (needs reprinttitle)

For the original question, the modification required is:

\renewbibmacro*{title}{%
  \ifthenelse{\iffieldundef{title}\AND\iffieldundef{subtitle}}
    {}
    {\printtext[title]{%
        \printfield[apacase]{title}%
        \setunit{\subtitlepunct}%
        \printfield[apacase]{subtitle}}%
     \setunit{\addspace}%
     \printfield{titleaddon}%
     \iffieldequalstr{entrytype}{book}%
       {\setunit{\addspace}\usebibmacro{bookaddinfo}}%
       {}%
     \ifthenelse{%
       \ifnameundef{author}\AND%
       \(\ifnameundef{editor}\AND\NOT\boolean{bbx:editorinauthpos}\)\AND%
       \ifnameundef{producer}\AND%
       \ifnameundef{director}\AND%
       \ifnameundef{writer}}
        {\newunit\newblock
         \usebibmacro{labelyear+extrayear}}
        {}}}

\DeclareFieldFormat{origyear}{%
 \mkbibparenss{\bibcpstring{origyear}~\thefield{origyear}%
 \iffieldundef{origtitle}
   {}%
   {\addcolon\addspace\printfield{origtitle}}}%
 }

\newbibmacro*{origyear}{%
  \ifthenelse{
      \NOT\iffieldundef{labelyear}
      \AND\NOT\iffieldsequal{labelyear}{origyear}
    \OR
      \NOT\iffieldsequal{title}{origtitle}}
    {\printfield{origyear}}
    {}%
}

\DefineBibliographyStrings{german}{%
   origyear = {Original erschienen}
}

This can be inserted in the preamble of your document.

For the extended version one has either to introduce new fields (this can be done,by modifying the data model, or by using the BibLaTeX facilities for related).

EDIT 1 and EDIT 2 To accommodate the case where the author of the original publication is different the first step is to modify the data model, this can be done with:

\begin{filecontents}{biblatex-dm.cfg}
\DeclareDatamodelFields[type=list, datatype=name,skipout=false]{origauthor}
\DeclareDatamodelEntryfields{origauthor}  
\end{filecontents}

This generates a file called biblatex-dm.cfg in the current directory with the instruction about how to extend BibLaTeX data model.

Notice that BibLaTeX provides a titleaddon field and this could be used to the extra information for the title ("Die Liebe" in the OP).

Eventually, one could add a field titletranslation for the selfmade translation, i.e., one can include the following two lines in the datamodel file.

\DeclareDatamodelField[type=field, datatype=literal,skipout=false]{titletranslation}
\DeclareDatamodelEntryfields{titletranslation}

Another possibility is to use an "unused" field, for example, reprinttitle. In what follow I'm going to use this option.

The next step is to modify the appropriate bibmacros. In this case, title and origyear for the formatting of the title (and related information about the original publication)

\renewbibmacro*{title}{%
  \ifthenelse{\iffieldundef{title}\AND\iffieldundef{subtitle}}
    {}
    {\printtext[title]{%
        \printfield[apacase]{title}%
        \setunit{\subtitlepunct}%
        \printfield[apacase]{subtitle}}%
     \setunit{\addspace}%
     \printfield{titleaddon}%
     \setunit{\addspace}%
     \printfield{reprinttitle}%
     \iffieldequalstr{entrytype}{book}%
       {\setunit{\addspace}\usebibmacro{bookaddinfo}}%
       {}%
     \ifthenelse{%
       \ifnameundef{author}\AND%
       \(\ifnameundef{editor}\AND\NOT\boolean{bbx:editorinauthpos}\)\AND%
       \ifnameundef{producer}\AND%
       \ifnameundef{director}\AND%
       \ifnameundef{writer}}
        {\newunit\newblock
         \usebibmacro{labelyear+extrayear}}
        {}}}

For originyear the first thing to do is to define the format. To this we check that originauthor is defined, and we set the punctuation accordingly:

\DeclareFieldFormat{origyear}{%
 \mkbibparens{\bibcpstring{origyear}~\thefield{origyear}%
 \ifnameundef{origauthor}
   {}
   {\addspace\bibstring{as}\addspace\printnames[FirstLast]{origauthor}}%
 \iffieldundef{origtitle}
   {}%
   {\ifnameundef{origauthor}
     {\setunit{\addcolon\addspace}}
     {\setunit{\addcomma\addspace}}%
     \printfield{origtitle}}}%
 }

Then we have to consider the cases when we have to output the information about the original publication (here the condition is that either the year, or the title, or the author(s) is different).

\renewbibmacro*{origyear}{%
  \ifthenelse{
      \NOT\iffieldsequal{labelyear}{origdateyear}
    \OR
      \NOT\iffieldsequal{title}{origtitle}
    \OR
      \NOT\ifnamesequal{author}{origauthor}
    }
    {\printfield{origyear}}
    {}%
}

Caveat A problem with the above solution is that not all bib entry types include instructions to format the information about the original publication using the above method. A more robust technique would be to use the facilities provided by BibLaTeX to handle related publications.

The last step is to use the appropriate value for the localisation strings origyear and as.

\NewBibliographyString{origyear,as}
\DefineBibliographyStrings{ngerman}{%
   origyear = {Original erschienen},
   as = {als}
} 

\DefineBibliographyStrings{american}{%
   as = {as} 
}

Finally, to change the rendering of names, we have to modify the formatting instructions for apaauthor

\DeclareNameFormat{FirstLast}{%
 \ifthenelse{\value{listcount}=\maxprtauth\AND\value{listcount}<\value{listtotal}}
    {\addcomma\addspace\ldots}
    {\ifthenelse{\value{listcount}>\maxprtauth\AND\value{listcount}<\value{listtotal}}
      {}
      {\iffirstinits
        {\usebibmacro{name:first-last}{#1}{#4}{#5}{#7}}
        {\usebibmacro{name:first-last}{#1}{#3}{#5}{#7}}}}
  \ifmorenames{\andothersdelim\bibstring{andothers}}{}}
