The “biblatex” and “csl” export processors support bibliography options through a property list attached to the ‘PRINT_BIBLIOGRAPHY’ keyword. For example,
#print_bibliography: :keyword algebra :type book
Values including spaces must be surrounded with double quotes. If you need to use a key multiple times, you can separate its values with commas, but without any space in-between:
#print_bibliography: :keyword "algebraic logic" :nottype article,book
The “biblatex” export processor accepts all options supported by
BibLaTeX’s \printbibliography
command, while the “csl” processor
accepts the following ones:
Print only entries whose keyword field contains all given keywords.
Print only entries whose keyword field does not contain any of the given keywords.
Print only entries whose type is ‘<entrytype>’. Entry type is the BibTeX/BibLaTeX entry type if this information is available (the entry was read from a BibTeX/BibLaTeX bibliography) and the CSL entry type otherwise.
Print only entries whose type is not among the given entry types. Entry type is determined as in the case of ‘:type’.
Print only entries whose CSL entry type (possibly based on a conversion from BibTeX/BibLaTeX to CSL) is ‘<entrytype>’.
Print only entries whose CSL entry type (possibly based on a conversion from BibTeX/BibLaTeX to CSL) is not among the listed entry types.
Print only entries for which the given
Emacs Lisp predicate returns a non-nil
value.
