[Tex/LaTex] Is it possible to suppress a specific field from bibtex .bbl in biblatex


I'm using biblatex, and am still very new at it.

I can't figure out how to suppress certain fields automatically generated from my bibtex file into my .bbl file. For instance, for all of my entries, I have a category Language in which I record the language that that work was written in. This is just for my own database, and I don't want this information listed in the References at the end of my article/book. But it gets listed anyway. The same is true of my notes field. Is there anyway to suppress a specific field so that it does not show up in the "List of References"?

I would write my own style, but my knowledge of programming/TeX is not even close to being able to do that. I've noticed there is a solution for the ISBN number (an option isbn=false), and this is exactly what I need, but for different fields.

The command \clearlist can be used to suppress a category. You can read more details in the documenation

texdoc biblatex

In the MWE below I have used filecontents* to create the bibliography, but if you already have a .bib file then you can delete these lines.

% this part creates mybib.bib
% delete these lines if you already have a .bib file
 author = "M. Abramowitz and I. A. Stegun",
 title = {Handbook of mathematical functions},
 publisher = "Dover publications",
 year = "1965",
 language="English" }
% end delete


\AtEveryBibitem{\clearlist{language}} % clears language
\AtEveryBibitem{\clearfield{note}}    % clears notes


hello world \cite{Ab_Steg}



The compilation sequence is

pdflatex myfile.tex
biber myfile.bcf
pdflatex myfile.tex
pdflatex myfile.tex

(You don't have to use the extensions if you don't want to.)
