Customize list in bibliography produced by biblatex

Question

I'm using BibLaTeX for bibliography management with bibstyle=gost-numeric which is not that common, but the problem is the same with more common bibstyle=numeric. I want a list produced with \printbibliography to have following property: text of each list entry should appear with the specific (fixed) horizontal shift. I need this to align it with bibliography title.

At the current point it fails to aligh a little bit, as you can see here:

(I'm using custom parindent). Any ideas how to achieve this?

The MWE is as follows

\documentclass [fontsize=14pt, paper=a4, pagesize, DIV=calc] {scrartcl}

\usepackage[english,russian]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T2A]{fontenc}

\usepackage{paratype}
\usepackage{indentfirst}

\usepackage{csquotes}
\usepackage[
  backend=biber,
  hyperref=auto,
  language=auto,
  citestyle=numeric,
  bibstyle=numeric,
]{biblatex}
\addbibresource{biblio.bib}

\newlength\MyIndent
\setlength\MyIndent{1.25cm}
\setlength{\parindent}{\MyIndent}
\addtokomafont{sectioning}{\hspace{\MyIndent}}

biblio.bib:

@MVBOOK{Lvo2003,
  author = {Львовский, Сергей Михайлович},
  title = {Набор и вёрстка в системе \LaTeX},
  year = {2006},
  language = {russian},
  publisher = {МЦНМО},
  location = {М.},
  hyphenation = {russian},
  url = {http://www.mccme.ru/free-books/llang/newllang.pdf}
}

Answer 1

You need to redefine the bibliography environment to achieve what you want.

So, add the following lines in your preamble

\defbibenvironment{bibliography}
  {\list
     {\printtext[labelnumberwidth]{%
    \printfield{prefixnumber}%
    \printfield{labelnumber}}}
     {\setlength{\labelwidth}{\labelnumberwidth}%
      \setlength{\leftmargin}{\labelwidth}%
      \setlength{\labelsep}{\dimexpr1.25cm-\labelwidth\relax}% <----- default is \biblabelsep
      \addtolength{\leftmargin}{\labelsep}%
      \setlength{\itemsep}{\bibitemsep}%
      \setlength{\parsep}{\bibparsep}}%
      \renewcommand*{\makelabel}[1]{\hss##1}}
  {\endlist}
  {\item}

It works both with the numeric bibstyle and with the gost-numeric one, since both have the same original definition.

MWE (note that babel has to be loaded after fontenc)

\documentclass [fontsize=14pt, paper=a4, pagesize, DIV=calc] {scrartcl}

\usepackage[utf8]{inputenc}
\usepackage[T2A]{fontenc}
\usepackage[english,russian]{babel}

\usepackage{paratype}
\usepackage{indentfirst}

\usepackage{csquotes}
\usepackage[
  backend=biber,
  hyperref=auto,
  language=auto,
  citestyle=numeric,
  bibstyle=numeric,
]{biblatex}
\addbibresource{biblio.bib}

\newlength\MyIndent
\setlength\MyIndent{1.25cm}
\setlength{\parindent}{\MyIndent}
\addtokomafont{sectioning}{\hspace{\MyIndent}}

\defbibenvironment{bibliography}
  {\list
     {\printtext[labelnumberwidth]{%
    \printfield{prefixnumber}%
    \printfield{labelnumber}}}
     {\setlength{\labelwidth}{\labelnumberwidth}%
      \setlength{\leftmargin}{\labelwidth}%
      \setlength{\labelsep}{\dimexpr1.25cm-\labelwidth\relax}% <----- default is \biblabelsep
      \addtolength{\leftmargin}{\labelsep}%
      \setlength{\itemsep}{\bibitemsep}%
      \setlength{\parsep}{\bibparsep}}%
      \renewcommand*{\makelabel}[1]{\hss##1}}
  {\endlist}
  {\item}
