With biblatex you can split a bibliography based on keywords using


as documented in Sectioning bibliography by type of referred item.

This seems to be hardwired to use the keywords field. Is there a way to divide the bibliography based on another field? Specifically, Mendeley inserts a mendeley-tags field that looks like:

mendeley-tags = {mytag1,mytag2,mytag3},

I have tried


but that doesn't work.

Is there a way to set this up?


With biblatex 2+ and biber 1+, you can do this in your preamble:

       \step[fieldsource=mendeley-tags, fieldtarget=keywords]
  • That gives me an error: ! Package keyval Error: fieldsource {mendeley-tags} undefined.

  • I had a feeling my method was dated. Looks like it is time to read the BibLaTeX and Biber manuals again.

  • It does work though, even if it gives an error! Thanks.

  • Try the editeed version - I don't think you need the braces I put in.

This is probably a dated answer as I have not really explored the potentially new data model in Biber 1.1.

If you create a new .conf file for Biber you should be able to map mendeley-tags to keywords

    <maps datatype="bibtex" map_overwrite="1">
        <map_step map_field_source="mendeley-tags" map_field_target="keywords"/>
  • Thanks. Where would I put that .conf file so that biber see's it?

    @user8786 you can put the file wherever you want (within reason) and then you point biber at the file with the -g option: biber -g /path/to/myconf/file/myconf.conf

    @DanielE.Shub Your answer is still valid. PLK's answer just uses the new, convenient feature of specifying a source map in the document preamble instead of the configuration file.

  • Yes, in some ways this is better if you want this to always happen to any document - that's what the biber config file is for.
