How to get a comma after the day in „urldate“: Accessed December 08, 2016

I recognized this, it helped me forward but did not solve my problem.

\thefield{urlday}\iscomma \addspace does not work
neither does \mkbibday{\thefield{urlday}\iscomma}\addspace

nejm is according to AMA, it is a derivative of „numeric-icomp“.

I already created the files /tex/latex/biblatex/biblatex.cfg, /tex/latex/biblatex/bbx/myStile.bbx and /tex/latex/biblatex/bbx/myStile.cbx with dummy-text: \ProvidesFile{biblatex.cfg} \endinput bzw. \ProvidesFile{myStyle.bbx} \RequireBibliographyStyle{nejm} \endinput and \ProvidesFile{myStile.cbx} \RequireBibliographyStyle{nejm} \endinput, an ran 'texhash TEXMFHOME' but I don‘t know what to put into *.cfg or *.bbx.

I use TeX Live 2015.20160320-1 and compile with XeLaTeX on Xubuntu 1604

biblatex-nejm uses a slightly unusual way of getting only the year. Try the following

\DeclareFieldFormat{urldate}{\mkbibparens{\bibstring{urlseen}\space#1}}

\DefineBibliographyExtras{english}{%
  \protected\def\mkbibdatelong#1#2#3{%
    \iffieldundef{#2}
      {}
      {\mkbibmonth{\thefield{#2}}%
       \iffieldundef{#3}
         {\iffieldundef{#1}{}{\space}}
     {\nobreakspace}}%
    \iffieldundef{#3}
      {}
      {\stripzeros{\thefield{#3}}%
       \iffieldundef{#1}{}{,\space}}%
     \iffieldbibstring{#1}
       {\bibstring{\thefield{#1}}}
       {\dateeraprintpre{#1}\stripzeros{\thefield{#1}}}}%
  \protected\def\mkbibdateshort#1#2#3{%
    \iffieldundef{#2}
      {}
      {\mkmonthzeros{\thefield{#2}}%
       \iffieldundef{#3}
         {\iffieldundef{#1}{}{/}}
         {/}}%
    \iffieldundef{#3}
      {}
      {\mkdayzeros{\thefield{#3}}%
       \iffieldundef{#1}{}{/}}%
     \iffieldbibstring{#1}
       {\bibstring{\thefield{#1}}}
       {\dateeraprintpre{#1}\mkyearzeros{\thefield{#1}}}}%
}

And load biblatex with the options alldates=year,urldate=long.

[Tex/LaTex] biblatex + verbose – urldate is getting ignored

At least with the standard verbose style, it works if you replace \printfield{urldate} with \printurldate. You might also want to change the format of urldate and load (as recommended in the biblatex manual) the babel package, here with the ngerman option.

\documentclass{article}

\usepackage[ngerman]{babel}

\usepackage[style=verbose]{biblatex}

\DeclareFieldFormat{url}{\url{#1}}
\DeclareFieldFormat{urldate}{#1}
\DeclareFieldFormat{formaturl}{\newline #1}
\DeclareFieldFormat{abrufurl}{\addcomma\space Abruf am #1}

\renewbibmacro*{url+urldate}{%
     \printtext[formaturl]{%
   \printfield{url}}%
     \printtext[abrufurl]{%
       \printurldate}%
}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
  url = {tex.stackexchange.com},
  urldate = {2012-05-22},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\nocite{*}

\begin{document}

\printbibliography

\end{document}

Instead of defining a new format including the string "Abruf am", you may also redefine existing bibliography strings:

\documentclass{article}

\usepackage[ngerman]{babel}

\usepackage[style=verbose]{biblatex}

\DeclareFieldFormat{url}{\newline\url{#1}}
\DeclareFieldFormat{urldate}{\addcomma\space\bibstring{urlseen}\space#1}

\DefineBibliographyStrings{german}{%
  urlseen = {Abruf am},
}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
  url = {tex.stackexchange.com},
  urldate = {2012-05-22},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\nocite{*}

\begin{document}

\printbibliography

\end{document}

Output for both examples:

[Tex/LaTex] Citing (author, journalabbr., year) needed

First thing to do is to add a field for the journal abbreviation to the article entrytype, journalabbr in the MWE. Therefore you need to declare a datamodel (an extra file; in the MWE I've used filecontents to simulate that) and you have to tell biblatex/biber to use it in the package options.

Then you have to modify the cite command, so it fits your needs. \citep from the authoryear-style (your citestyle) uses the \cite command. There you just have to add a switch, which checks if the field journalabbr is empty or not, and prints it out or not.

Last but not least you have to add the abbreviation fields to the entries.

MWE:

\begin{filecontents}{min.bib}
@article{boisson2003unexpected,
  title={Unexpected protein families including cell defense components feature in the N-myristoylome of a higher eukaryote},
  author={Boisson, B. and Giglione, Carmela and Meinnel, Thierry},
  journal={Journal of Biological Chemistry},
  journalabbr={JBC},
  year={2003},
  publisher={ASBMB}
}
\end{filecontents}

\begin{filecontents}{authorjabbryear.dbx}
\ProvidesFile{authorjabbryear.dbx}
\DeclareDatamodelFields[type=field,datatype=literal]{journalabbr}
\DeclareDatamodelEntryfields[article]{journalabbr}
\end{filecontents}

\documentclass[fontsize=11pt, paper=a4, ngerman, DIV=calc]{scrartcl}
\usepackage[scaled]{helvet}
\renewcommand*\familydefault{\sfdefault}
\usepackage{fixltx2e}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

,datamodel=authorjabbryear%added!
] {biblatex}

\DefineBibliographyStrings{ngerman}{ andothers = {{et\,al\adddot}} }

\renewbibmacro*{cite}{%from authoryear.cbx
  \iffieldundef{shorthand}
    {\ifthenelse{\ifnameundef{labelname}\OR\iffieldundef{labelyear}}
       {\usebibmacro{cite:label}%
        \setunit{\addspace}}
       {\printnames{labelname}%
        \setunit{\nameyeardelim}}%
     \iffieldundef{journalabbr}{}{%
        \printfield{journalabbr}%
        \setunit{\nameyeardelim}%
        }%
     \usebibmacro{cite:labelyear+extrayear}}
    {\usebibmacro{cite:shorthand}}}

\addbibresource{min.bib}

\begin{document}

\citep{boisson2003unexpected} 

How it should look like: 

(Boisson et al., JBC, 2003)

\printbibliography

\end{document}
