Footnote citation and bibliography different styles

Question

I am working on my Master’s thesis using the book class. I need to write the citations both as footnotes in the text and to collect them at the end in the Bibliography chapter. To do this, I need two different styles, one for the footnote citations and one for the bibliography entries.

I have created the footnote style that I need thanks to the xpatch package. However, I do not understand how to change the style of the entries in the bibliography at the end of the thesis (at the moment, the two styles are the same).

For the footnote citations, they have to appear as:

N. Surname et al., Title of the paper. Title of the journal, Editor, Year, pages

For the bibliography entries, they have to appear as:

Surname Name, Title of the paper. Title of the journal, Editor, Year

This is the MWE (the footnote citation style is correct, the bibliography style is wrong). I compile using XeLaTeX and Biber:

\documentclass[a4paper,12pt]{book}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

The footnote citations should look like this (the first is a paper and the second is a book):

The bibliography citations should look like this (the first is a paper and the second is a book):

Answer 1

There are still a few aspects of the style that are a bit unclear to me, but I guess the following should get you pretty far already.

As I read the question it is mainly about the name format. The name format you need to change is called sortname. In the citation we need a format that gives us given name inital and family name (the new format g-family).

cite:full is just a copy of the cite:full from verbose.cbx, ll. 93-99, with the name format changed.

In the bibliography we want the "family given" name order and no comma between the parts (that is controlled by \revsdnamepunct).

I slightly rewrote your method to put commas between the elements of the reference: It is slightly easier and cleaner with \renewcommand*{\newunitpunct}{\addcomma\space}.

\documentclass[a4paper,12pt]{article}
\usepackage[english]{babel}
\usepackage[style=verbose,
  maxbibnames=999,
  doi=false,
]{biblatex}

\DeclareNameFormat{g-family}{%
  \usebibmacro{name:given-family}
    {\namepartfamily}
    {\namepartgiveni}
    {\namepartprefix}
    {\namepartsuffix}%
  \usebibmacro{name:andothers}}

\renewbibmacro*{cite:full}{%
  \usebibmacro{cite:full:citepages}%
  \printtext[bibhypertarget]{%
    \usedriver
      {\DeclareNameAlias{sortname}{g-family}}
      {\thefield{entrytype}}}%
  \usebibmacro{shorthandintro}}

\usepackage{xpatch}
\xpatchbibmacro{name:andothers}{%
  \bibstring{andothers}%
}{%
  \bibstring[\emph]{andothers}%

\renewcommand*{\newunitpunct}{\addcomma\space}
