Creating a magazine

Good afternoon! My name is Marius-Constantin POPA, a user running your wonderful office suite, and I want to know what I have to do in order to create a magazine properly with LibreOffice. I want to create a magazine with articles from many fields: religion, health, psychology, and so on. In order the readers of my magazine to know which kind of article they read (which field studies that kind of information), I want to emphasise these fields in some way: by writing their names at the top of the article, in the header,close to other kind of information. What should I do to fulfill my wish? Thanks in advance.

There are a couple of templates in the site:

http://templates.libreoffice.org/template-center?getCategories=&getCompatibility=any&sort_on=positive_ratings&path=%2FLibreOffice-Templates%2Ftemplate-center&portal_type=PSCProject&SearchableText=magazine

But I want to create a magazine without using a template? How can I do that?
