Prints bibliographic information stored in BibEntry objects in BibLaTeX style


# S3 method for BibEntry
print(x, .opts = list(), ...)



a BibEntry object


a list of formatting options from BibOptions. Possible options are

  • style - character string naming the printing style. Possible values are plain text (style “text”), BibTeX (“Bibtex”), BibLaTeX (“Biblatex”), a mixture of plain text and BibTeX as traditionally used for citations (“citation”), HTML (“html”), LaTeX (“latex”), “markdown”, “yaml”, R code (“R”), and a simple copy of the textVersion elements (style “textVersion”, see BibEntry)

  • - character string specifying BibLaTeX style to use for formatting references. Possible values are “numeric” (default), “authoryear”, “authortitle”, “alphabetic”, “draft”. See section 3.3.2 of the BibLaTeX manual.

  • sorting - how should the entries in x be sorted? See sort.BibEntry.

  • max.names - maximum number of names to display for name list fields before truncation with “et al.”.

  • first.inits - logical; if true only initials of given names are printed, otherwise full names are used.

  • dashed - logical; for .bibstyle = "authoryear" or .bibstyle = "authoryear" only, if TRUE duplicate author and editor lists are replaced with “---” when printed.

  • no.print.fields character vector; fields that should not be printed, e.g., doi, url, isbn, etc.


extra parameters to pass to the renderer.


setting max.names to value is equivalent to setting maxnames=value and minnames=value in BibLaTeX.

Custom BibLaTeX styles may be defined using the function bibstyle. To fully support BibLaTeX, the created environment must have functions for formatting each of the entry types described in BibEntry.
