This is my first post here, but long time lurker as they say. Here is my problem: When citing an @incollection in biblatex-apa, I am getting the volume editor's(s') name(s) printed twice in the reference list. MWE:

    %!TEX TS-program = xelatex
%!TEX encoding = UTF-8 Unicode
%TC:incbib
\documentclass{article}
\usepackage{polyglossia} 
\setdefaultlanguage[variant=american]{english}
\usepackage{csquotes}
\usepackage[style=apa, backend=biber]{biblatex}

\usepackage{filecontents}
\begin{filecontents}{mwe.bib}
@incollection{Turing1954,
    Author = {Turing, Alan},
    Booktitle = {The Essential {Turing}: Seminal Writings in Computing, Logic, Philosophy, Artificial Intelligence, and Artificial Life plus The Secrets of Enigma},
    Crossref = {Turing2004},
    Origdate = {1954},
    Pages = {576-595},
    Title = {Solvable and Unsolvable Problems},
}
@collection{Turing2004,
    Date = {2004},
    Editor = {Copeland, B. Jack},
    Location = {Oxford},
    Publisher = {Oxford Univeristy Press},
    Shorttitle = {The Essential {T}uring},
    Title = {The Essential {T}uring: Seminal Writings in Computing, Logic, Philosophy, Artificial Intelligence, and Artificial Life Plus the Secrets of Enigma},}
\end{filecontents}

\addbibresource{mwe.bib}

\begin{document}
\nocite{*}
\printbibliography
\end{document}

This gives me the following result, when compiled with Biber 2.14; XeTeX, Version 3.14159265-2.6-0.999991 (TeX Live 2019); BibLaTeX 3.14; BibLateX-APA 9.2; and csquotes 5.2j. The editor's name given once in brackets and again without brackets: Reference list for Turing paper and Edited volume

How can I get rid of the name in the brackets? Any help will be appreciated!

  • This does seem weird to me. Does using @book and @inbook give acceptable output? (It's a little different.) – David Purton Dec 20 '19 at 01:05
  • BTW, you don't need the booktitle field in your Turing1954 entry as the crossref field handles this automatically. – David Purton Dec 20 '19 at 01:08
  • Welcome to TeX.se and thanks for adding a compilable example. This seems to be a recent change. I get correct output with TL 2018 (biblatex 3.12; biber 2.12; apa v 7.7) but not with TL 2019 (biblatex 3.14; biber 2.14 apa 9.2). – Alan Munn Dec 20 '19 at 02:51
  • This looks indeed wrong, please report this as a bug at https://github.com/plk/biblatex-apa/issues (ideally you would check which position of the editors is correct in your APA manual). Note that biblatex-apa (style=apa) now (i.e. from version 9 onwards) produces 7th-edition APA style, if you want 6th-edition APA style, you need to use biblatex-apa6 (style=apa6). – moewe Dec 20 '19 at 06:49
  • Thanks for your replies! I will report it as a bug as moewe suggests. Both APA 6th and 7th use: ...A. Editor (Ed.), Title of Book... etc.For 7th see https://apastyle.apa.org/instructional-aids/reference-guide.pdf – aswright Dec 20 '19 at 13:22

This issue has been fixed in biblatex-apa v9.3 after you reported it at https://github.com/plk/biblatex-apa/issues/86.

Versions 9.0 and above of biblatex-apa implement APA style from the 7th edition of the manual, which differs from the 6th edition APA style that versions up to 8.0 would implement. 6th edition APA style can now be obtained from biblatex-apa6 (style=apa6,).

7th edition APA style has a simplified type scheme that allows biblatex-apa to treat @book and @collection as well as @inbook and @incollection exactly alike. Initially it was forgotten to make sure that @collection and @incollection are handled properly as well, since in the output they are equivalent to the ...book types. Indeed biblatex-apa didn't even have a driver for @collection.

In version 9.3 @collection gets remapped to @book and @incollection is remapped to @inbook. This means that the .bib file can and should still use the correct entry types (for portability), but internally only the @...book types exist and the other types are remapped. This is not something a user should normally worry about, but it is something to keep in mind if one wants to modify the style (I recommend not to modify biblatex-apa or to take it as a basis for building a customised style: biblatex-apa was specifically designed to implement the APA guidelines and has to do some work to do that properly, it was not intended to be customised beyond APA requirements).

With biblatex-apa 9.3 or above the MWE looks as expected (note that I case protected entire words and not just first letters with curly braces, this is preferable since braces could inhibit kerning [at least with some engines, LuaTeX is different]: BibTeX loses capitals when creating .bbl file).
