I am puzzled why I do not get the same style for entries of books and articles in the bibliography in the following MWE:
% !TeX program=lualatex
\documentclass{scrartcl}
\usepackage{fontspec}
\usepackage[style=numeric,url=false]{biblatex}
\AtEveryBibitem{\clearfield{month}}
\usepackage[main=ngerman,english]{babel}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@Article{atkins1980,
author = {Atkins, M},
title = {Atlas of continuous cooling transformation diagrams for engineering steels},
journal = {American Society for Metals},
year = {1980},
pages = {260},
}
@Book{aaronson2010,
title = {Mechanisms of Diffusional Phase Transformations in Metals and Alloys},
publisher = {{CRC} Press},
year = {2010},
author = {Hubert Aaronson and Masato Enomoto and Jong Lee},
month = {may},
doi = {10.1201/b15829},
}
@Article{kolmogorov1937,
author = {Kolmogorov, Andrei Nikolaevich},
title = {On the statistical theory of the crystallization of metals},
journal = {Bull. Acad. Sci. USSR, Math. Ser},
year = {1937},
volume = {1},
pages = {355--359},
}
\end{filecontents}
\addbibresource{\jobname.bib}
\begin{document}
\cite{atkins1980,aaronson2010,kolmogorov1937}
\printbibliography
\end{document}
Edit: As @moewe explained, there's a good reason for the enquoted upface vs. non-enquoted italic titles, though it makes for an inconsistent look of the bibliography and it's not the style I was recommended to use (which was what I aimed for in the original question). Upon a quick browse of some textbooks from my field, I have not found the enquoted title style for books a lot, let alone in German books. Taking all this into account, I'd like to apply the following minor changes to the default:
- The title of sources that belong to a container should not be in quotes
- The year should be consistently in parentheses
- The first names should be abbreviated
:instead of '.' between author and title
What do I need to specify as package options and what do I have to adjust by hand in the bibtex entries?

texdoc biblatexon my own, I'd like to understand why there is a such a big difference for books and articles in the first place. – Christoph90 Mar 01 '18 at 12:32@articles in parentheses). I guess it comes from the fact that for@articles thevolumeis much more important, and given avolumethe year is almost redundant. For@books and friends, however, volume plays a different role (if at all) and the year is more important than for@article. – moewe Mar 01 '18 at 12:49biblatex's standard styles do not follow a particular style guide. I assume it is fair to say that the styles were influenced by (BibTeX) bibliography styles out there at the time and the tastes of the author. We can't really say why a particular decision was taken and Philipp Lehman has unfortunately vanished from the TeX world, so we can't ask him either. I believe that question about they whys of design decisions are off topic here anyway. – moewe Mar 01 '18 at 12:54biblatexstandard styles are just one particular style and there is no expectation that they work for everyone. ... – moewe Nov 30 '20 at 07:09biblatexis to make it easy for people to change the styles. It is hard to answer the 'why' questions conclusively given that the originalbiblatexdeveloper (who wrote the standard styles) is no longer active. So any answers you get about that are going to be either lucky finds of some quotes where he explains his choices or quite a bit of speculation. – moewe Nov 30 '20 at 07:13
