Q. what rights should belong to every human being

I can point you in the direction of a couple of databases which will help you explore the broad topic of human rights, to focus in on a few specific aspects.

Go to the databases guide below.  The databases are in alphabetical order, so click on 'g' for Gale and 'f' for Facts on File.  Two databases, Gale in Context Opposing Viewpoints & Facts on File both discuss human rights and can help with this.

Gale in Context Opposing Viewpoints has a topic overview, pro and con articles, academic articles and more.

Facts on File has an article on Human Rights, then some updates and sidebars.
