This question is similar to Suppress “In:” biblatex and biblatex: How to remove the parentheses around the year in authoryear style?, but I don’t want to change the format of bibliography entries completely, but would rather like it to deal better with some cases.
If I have a BibTeX entry of type @article which does not give a journal title (e. g. in the journal field), as it happens with pure e-print articles, the entry is still printed of the form “In: (<year>)” in the bibliography.
For example, with this BibTeX entry, the entry is printed as follows in the bibliography:
D. Wegman. “Deviations of exact neutrino textures using radiative neutrino masses”. In: (2017). arXiv: 1711.08004 [hep-ph].
The part “In: (2017).” looks very suboptimal. How could the formatting be improved for entries without a journal title?
@articleentry. It is an@online. See the arXiv-only examples inbiblatex-examples.bib.@articleis only for papers published in a journal,@articles always have ajournal(andvolume). If a paper does not have ajournalthat means it was not published in a journal and so@articleis inappropriate – moewe Feb 13 '18 at 14:02journalfield, the entry shouldn't be given the type@article. Period. – Mico Feb 13 '18 at 14:03
