15.3.1 Bibliography options in the ‘biblatex’ and ‘csl’ export processors
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.
The 'csl' processor accepts the following options:
':keyword <keyword(,keyword2...)>'
Print only entries whose keyword field contains all given keywords.
':notkeyword <keyword(,keyword2...)>'
Print only entries whose keyword field does not contain any of the given keywords.
':type <entrytype>'
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.
':nottype <entrytype(,entrytype2...)>'
Print only entries whose type is not among the given entry types. Entry type is determined as in the case of ':type'.
':csltype <entrytype>'
Print only entries whose CSL entry type (possibly based on a conversion from BibTeX/BibLaTeX to CSL) is '<entrytype>'.
':notcsltype <entrytype(,entrytype2...)>'
Print only entries whose CSL entry type (possibly based on a conversion from BibTeX/BibLaTeX to CSL) is not among the listed entry types.
':filter <predicate>'
Print only entries for which the given Emacs Lisp predicate returns a non-nil value.
