 : #+print_bibliography:
 
+The "biblatex" and "csl" export processors support passing additional
+bibliography options through a property list attached to the
+=PRINT_BIBLIOGRAPHY= keyword.  E.g.,
+
+: #+print_bibliography: :type book :keyword algebra
+
+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 algebra,logic :title "Primary Sources"
+
+A document may contain more than one =PRINT_BIBLIOGRAPHY= keywords
+with or without additional options.  The "biblatex" export processor
+accepts all options supported by BibLaTeX's ~\printbibliography~
+command, while the "csl" processor accepts the following ones:
+
+- =: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.
