Bibliographies are complicated and many different styles exist. Creating properly formatted bibliographies from raw bibliography entries is especially challenging. (This parameter does not apply to formatting bibliomixed entries.)

default

The default style. This is controlled by the biblioentry template. See $v:templates. All biblioentry elements will be processed in m:biblioentry mode.

iso690

Attempts to implement ISO 690 bibliographic formatting. All biblioentry elements will be processed in m:biblio690 mode. This is adapted from the examples in Bibliography according to ISO 690 and ISO 690-2 standards.

The default style specified by $bibliography-style can be overridden on a case-by-case basis with the db processing instruction using the bibliography-style pseudo-attribute. This must appear in the bibliography or bibliolist that contains the entries.
