A bibliography within the text area (e. g. at the beginning of the chapter) can be tagged with the <listBibl> element. Each bibliographic entry is realized within <listBibl> by <bibl>[...]</bibl>. The use of the <listBibl> element is optional.
Bibliographic References in the Continuous Text (Level 3)
The <bibl> element can also be used in the continuous text to point out bibliographic information. By means of a subordinate <ref> element, it can be referred to an external (more detailed) bibliographic reference. The use of <bibl> and a subordinate <ref> in the continous text is optional (level 3).
To tag bibliographies at the end of the book (bibliography in the <back> area) see chap. Appendix.
