I'm using biblatex and biber with the following definitions:

  % firstinits=true,
  backrefpage  = {cited on p.},
  backrefpages = {cited on pp.}

I have a bibliography item defined like this:

  author = "Apollinari, G and Béjar Alonso, I and Brüning, O and Lamont, M and
    Rossi, L",
  title  = "{High-Luminosity Large Hadron Collider (HL-LHC):
    Preliminary Design Report}",
  publisher = "CERN",
  address   = "Geneva",
  series    = "CERN Yellow Reports: Monographs",
  year      = "2015",
  url       = "https://cds.cern.ch/record/2116337",
  doi       = "10.5170/CERN-2015-005"

which comes out like this:

enter image description here

Is it possible to define a new field called cds that should work like doi, so in the .bib file I could write cds = "2116337" and it would add "CDS: 2116337" to the item in the bibliography with the number linked to the URL?

  • Is what you did so different from the answer there that it warrants a new answer of its own or would you say it would also be OK to close this question here as a duplicate?

For posterity, here is the listing of what I did, based on the answer here, which was suggested in the comments.

Inside biblatex-dm.cfg, which can be put in the same directory as the main .tex file,


In the main .tex, after \usepackage{biblatex}, before the \begin{document},
