[Tex/LaTex] How to add an electonic identifier (eid) field to inproceedings type in biblatex

biblatexbibliographies

By default, in biblatex, inproceedings entries do not support the eid field (electronic identifier). In article entries, the eid is printed instead of the page number, see the following MWE:

\documentclass{scrbook}

\usepackage[ngerman]{babel} 
\usepackage[T1]{fontenc}
\usepackage[ansinew]{inputenc}

\usepackage[%
  citestyle = alphabetic, 
  bibstyle = ieee-alphabetic,
  labelalpha = true,
  defernumbers = true,
  backend = biber,
  maxalphanames = 1,
  firstinits = true,
  abbreviate = true,
  bibencoding = utf8,
  dateabbrev = true,
  maxbibnames = 10,
  minbibnames = 3
  %eprint = true
]{biblatex}%

\bibliography{./Literatur.bib}

\DeclareFieldFormat{eid}{Art. \addnbspace #1}

\begin{filecontents}{./Literatur.bib}

@article{ibrahim_spectral_2010,
  title =    {Spectral imaging method for material classification
                  and inspection of printed circuit boards},
  author =   {Ibrahim, Abdelhameed and Tominaga, Shoji and
                  Horiuchi, Takahiko},
  journal =  {Optical Engineering},
  volume =   49,
  number =   5,
  eid =      05720,
  year =     2010
}

@inproceedings{gruna_optical_2012,
  author =   {Gruna, Robin and Beyerer, Juergen},
  title =    {Proc. Optical feature extraction with illumination-encoded
                  linear functions},
  series =   {Proceedings of SPIE},
  year =     2012,
  booktitle =    {Image Processing: Machine Vision Applications V},
  volume =   8300,
   eid =     830004
}

\end{filecontents}

How can I modifiy the proceedings entry type to print the eid field like in articles (instead of page numbers at the same position)?

Best Answer

We can redefine the macro that prints the page numbers and chapter to also output the eid via

\renewbibmacro*{chapter+pages}{%
  \printfield{chapter}%
  \setunit{\bibpagespunct}%
  \printfield{eid}
  \setunit{\bibpagespunct}%
  \printfield{pages}%
  \newunit}

This also allows for eid and pages to be present at the same time. (Note that we essentially treat eid and pages the same in the sense that both are preceded by \bibpagespunct and not the standard \newunitpunct.)

Use an existing field (`part`)

If you use the part field for tome information¹, there is not a lot to be done in the standard styles. If you have a non-standard/custom style that moves around the part information though, you would need to tell us more about it.

These four lines should do what you want. They redefine the string part to be "tomo" and print ", tomo #" after the volume.

\DefineBibliographyStrings{italian}{%
  part = {tomo},
}
\DeclareFieldFormat{part}{\addcomma\space\bibstring{part}\space #1}

All the standard styles use the sequence

\printfield{volume}%
\printfield{part}%

to print part information, so we should be fine.

(Normally, putting \addcomma and the like in \DeclareFieldFormat is frowned upon, but the part field seems to be special insofar that the default format is {.#1} and that there is no other punctuation inserted between volume and part by any of the standard styles.)

Your bib entry would be

@InProceedings{bertolini:1992,
  author         = "Francesco Bertolini",
  title          = "Società di trasmissione orale: mito e folclore",
  booktitle      = "Lo spazio letterario della Grecia antica",
  editor         = "G. Cambiano and L. Canfora and D. Lanza",
  publisher      = "Salerno",
  location       = "Roma",
  year           = "1992",
  volume         = "1",
  part           = "2",
  pages          = "47--75",
}

¹ The biblatex documentation states on page 21, §2.2.2 Data Fields,

part (field (literal)) The number of a partial volume. This field applies to books only, not to journals. It may be used when a logical volume consists of two or more physical ones. In this case the number of the logical volume goes in the volume field and the number of the part of that volume in the part field.

Map the field to an existing field (`part`)

You could also map the field tome to part thus creating an alias for input purposes

\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map{
      \step[fieldsource=tome]
      \step[fieldset=part, origfieldval]
    }
  }
}

The sample entry might look like this then

@InProceedings{bertolini:1992,
  author         = "Francesco Bertolini",
  title          = "Società di trasmissione orale: mito e folclore",
  booktitle      = "Lo spazio letterario della Grecia antica",
  editor         = "G. Cambiano and L. Canfora and D. Lanza",
  publisher      = "Salerno",
  location       = "Roma",
  year           = "1992",
  volume         = "1",
  tome           = "3",
  pages          = "47--75",
}

For more general purposes, biblatex defines the five generic fields usera to userf (as well as lista to listf for lists fields and namea to namec for names). While it might be awkward to use these fields in the input .bib file, where more useful names are expected, they are useful for internal remapping.

Declare a new field

If you absolutely insist on creating a new data field tome, create a new datamodel file, tome.dbx, with the following content and put it somewhere LaTeX can find it (this is necessary since version 2.9, before that it was possible to use datamodel commands directly in the document, but this is not guaranteed to work and therefore strongly discouraged, see Data model macro cannot be used in preamble; LaTeX will be able to find the .dbx file if you place it in the same folder as your main .tex document, other options to make the file globally available are discussed in https://texfaq.org/FAQ-inst-wlcf).

\ProvidesFile{tome.dbx}[2019/20/02 add tome field to biblatex data model]

\DeclareDatamodelFields[type=field,datatype=literal]{tome}
\DeclareDatamodelEntryfields{tome}

(In the MWE below this file is created automatically using the filecontents package.)

We then have to load biblatex with the option datamodel=tome in order to get load the correct datamodel where tome is defined. Alternatively, you can put the above lines into biblatex-dm.cfg (see How to include price in bibliography?).

Again we use localisation strings

\NewBibliographyString{tome}
\DefineBibliographyStrings{italian}{%
  tome = {tomo},
}

\DeclareFieldFormat{tome}{\bibstring{tome}\space #1}

We will then have to patch all the drivers/macros to include tome information, that is quite a task...

We renew some macros

\renewbibmacro*{maintitle+title}{%
  \iffieldsequal{maintitle}{title}
    {\clearfield{maintitle}%
     \clearfield{mainsubtitle}%
     \clearfield{maintitleaddon}}
    {\iffieldundef{maintitle}
       {}
       {\usebibmacro{maintitle}%
    \newunit\newblock
    \iffieldundef{volume}
      {}
      {\printfield{volume}%
     \setunit{addcomma\space}%
     \printfield{tome}
           \printfield{part}%
           \setunit{\addcolon\space}}}}%
  \usebibmacro{title}%
  \newunit}

\renewbibmacro*{maintitle+booktitle}{%
  \iffieldundef{maintitle}
    {}
    {\usebibmacro{maintitle}%
     \newunit\newblock
     \iffieldundef{volume}
       {}
       {\printfield{volume}%
     \setunit{addcomma\space}%
     \printfield{tome}
        \printfield{part}%
        \setunit{\addcolon\space}}}%
  \usebibmacro{booktitle}%
  \newunit}

And add tome to the drivers

\newcommand*{\addtometo}[1]{%
  \xpatchbibdriver{#1}
    {\printfield{volume}}
    {\printfield{volume}%
     \setunit{\addcomma\space}%
     \printfield{tome}}
    {}
    {\typeout{failed to add tome to #1 driver}}
}
\addtometo{inproceedings}
\addtometo{book}

That much hassle probably is not worth it as we have part that seems to do what you want rather well.
