When using the @online bibliography entry in biblatex the actual URL always gets prefixed with URL: (for an image see the first link below). I'd like to know how I can remove that prefix.

While searching on the web for this I stumble upon Delete "URL:" prefix in biblatex online entries? include date visited? and How to remove 'URL' prefixed before the URL in bibliography.

The answer to the first example doesn't really care about answering how to get rid of the URL: prefix (EDIT: Actually it does but the solution is quite hidden in the rest of what gets done there) and the solution in the second link (using \def\urlprefix{}) doesn't work.

Does somebody know how I can turn that prefix off? So what I want is something like this:

[1] 12. Oct. 2018. https://tex.stackexchange.com/questions/ask

And here's an example-entry:

    date = {2018-10-28},
    url = {http://www.galleries.com/Scheelite}

PS: I'm not sure how important this is but I am using latexmk with the -lualatex option (so lualatex will be used to compile the document) and biber as the backend for biblatex.

    Untested: \DeclareFieldFormat{url}{\url{#1}}. However, probably the proper way to deal with it is to redefine the localized string, for which a MEWB would be required to reduce the guesswork.

    Mhhh, upon reading the first linked question (tex.stackexchange.com/q/336317/35864) the answer there does exactly the right thing (amongst others, so it might be a bit harder to figure out which bit of code takes care of what result): \DeclareFieldFormat{url}{\url{#1}} and definitely gets rid of the "URL:". If it does not work for you, please show us a short example document of what you have tried (tex.meta.stackexchange.com/q/228/35864 and tex.meta.stackexchange.com/q/4407/35864)

  • @moewe Indeed... Didn't find that little line in all the other stuff that was going on in that answer.

    Thank you very much for taking the time to adjust your question to point out that the answer in fact does provide an adequate answer. I was a bit uncomfortable with the claim that the answer does not care to address the problem (I'm not a native speaker, so my connotations when I read that line might have been too strong, but I felt that it was unfair on the answer). The question and answer serve as a good example why it makes sense to only ask one specific thing per question and not several things (however closely they are related).

You can adjust the field format for the url field. The default is


So you could try

\usepackage[style=authoryear, backend=biber]{biblatex}

  • Add \urlstyle{sf} to change the font from courier to something more attractive (and tighter).
