# How can I get the name of every editor in front of the book title in InCollection from JabRef?

I'm compiling a bibliography using Biblatex, and I cite many articles that are part of collections/edited books. According to my referencing guide, I need Last Name, First name initial. (Year). "Title". In: Last Name, First Name Initial (ed.s.), book title. Location: Publisher, pages.

Most of that is fine, but my \printbibliography command will only let me put editors before title with the "first author et al.", but I need every editor listed before the book title.

I use JabRef, where I use InCollection as a format. My preamb in Latex looks like the following:

\documentclass[a4paper, 12pt]{article}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{soul}
\usepackage{tabularx}
\usepackage{dcolumn}
\usepackage{graphicx}
\usepackage[margin=2.5cm]{geometry}
\usepackage{fancyhdr}
\usepackage{setspace}
\usepackage{listings}
\usepackage{color}
\usepackage{subcaption}
\usepackage{hanging}
\usepackage[english]{babel}
\usepackage[babel]{csquotes}
\PassOptionsToPackage{hyphens}{url}\usepackage{hyperref}

\onehalfspacing
\pagestyle{fancy}

\usepackage{fontspec}
\setmainfont{Times New Roman}
\usepackage[style=ext-authoryear, firstinits=true,  backend=biber,
innamebeforetitle = true]{biblatex}

\DeclareFieldFormat{editortype}{\mkbibparens{#1}}

\DeclareFieldAlias{translatortype}{editortype}
\DeclareDelimAlias{translatortypedelim}{editortypedelim}

\renewbibmacro{in:}{%
\ifentrytype{article}{}{\printtext{\bibstring{in}\intitlepunct}}}
\nocite{*}


I have attached two of my sources below, as I have entered them in JabRef.

@InCollection{Andreadisetal,
author    = {Andreadis, I. and Cremonesi, C. and Kartsounidou, E. and Kasprowicz, D. and Hess, A.},
title     = {Attitudinal and Behavioral Responses to Populist Communication: The Impact of Populist Message Elements on Populist Attitudes and Voting Intentions},
booktitle = {Communicating populism: comparing actor perceptions, media coverage, and effects on citizens in Europe},
year      = {2019},
publisher = {Routledge},
location  = {New York},
editor   = {Reinemann, C. and Stanyer, J. and Aalberg, T. and Esser, F. and De Vreese, C.H.},
}

@InCollection{Bruns&Highfield,
author    = {Bruns, A. and Highfield, T.},
title     = {Is Habermas on Twitter? Social Media and the Public Sphere},
booktitle = {The Routledge Companion to Social Media and Politics},
year      = {2016},
editor    = {Bruns, A. and Enli, G. and Skogerbø, E. and Larsson, A.O. and Christensen, C.},
publisher = {Routledge},
location  = {New York},
}


Is there a way to specify to LaTeX that I want all editor names before book title, not just "et al." before book title?

• This is better-suited on TeX - LaTeX. Flag it for moderator attention and request migration. – Werner Sep 24 '19 at 15:54

Based on https://tex.stackexchange.com/a/287780/36296 the following redefinition of the bbx:in:editor macro will show up to 42 editors - if you need more increase this number as necessary.

Please also note that the option firstinits is deprecated, please use giveninits instead.

• Without this modification the number of editors printed obeys the maxbibnames (or maxnames) setting. Especially if the parent @collection appears in the bibliography in its own right having everything obey maxbibnames makes for a more consistent bibliography. – moewe Sep 28 '19 at 9:59
