For a particular journal which I am submitting to, I must use the Chicago author-date style. So I am using biblatex-chicago style.
But each bibliography item must have double indentation, as shown in the attached image.
I just don't know what to do to fulfill that format requirement, so I would be much obliged if someone helps me out.
philosophy-modern from the biblatex-philosophy style family is a good start for this.
With only little change (the publocformat=loccolonpub option - which is specific to biblatex-philosophy, and \renewcommand*{\newunitpunct}{\addperiod\space}) we get
\documentclass[american]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}
\usepackage[backend=biber, style=philosophy-modern, publocformat=loccolonpub]{biblatex}
\addbibresource{biblatex-examples.bib}
\renewcommand*{\newunitpunct}{\addperiod\space}
\begin{document}
\cite{sigfridsson,worman,geer,knuth:ct:a,knuth:ct:b,knuth:ct:c,companion,westfahl:space,brandt}
\printbibliography
\end{document}
biblatex-philosophy'sphilosophy-modernstyle. There are lot of options to customise its output and the unmodified output looks quite similar to what you want. Depending on how your journal processes subscriptions it might, however, be a waste of time and effort to try and mirror their output if they do the final typesetting. Maybe you should ask the staff how and if they handle LaTeX submissions and in particular what to do about the bibliography. – moewe Mar 16 '17 at 8:02
