1. In regular book publications (using the bywords: "book" and "bookhrvd") put:
   - the number and title of of the running chapter in the header of even pages, 
   - the number and title of the running subchapter in the header of odd pages (3,5,7...).

2. In editorial books used for collective works ("collection", "*hrvd") and conference proceedings (proceedings) put:
   - the names of the authors (J. Brown) in the header of even pages, and 
   - the title of the chapter (paper) in the header of odd pages.

3. The bibliographical basis is formed by the following two files:
   pwnt.bst - using numerical references, and 
   pwnthrvd.bst - using the harvard style.

4. All the templates use the same version of the style file: pwnt_en.cls. 
   As can be seen in the template tex file (sample.tex), the preambule defines the type of the book:

\documentclass[book]{pwnt_en} - for book issues (with numerical references),
\documentclass[book,hrvd]{pwnt_en} - for books using the harvard style of the bibliographical referencing, 
\documentclass{pwnt_en} - for collective editorial issues with the numerical referencing (the optional format),
\documentclass[hrvd]{pwnt_en} - for collective editorial issues with the harvard bibliography,
\documentclass[proc]{pwnt_en} - for conference proceedings.
