Copyright law is designed to ascribe exclusive rights to the creator of a work.

it protect the rights of authors creativity

Violating copyright law and defending your rights are opposite ideas.

The legal impact of breaking copyright law varies from country to country, but usually consists of fines, and in extreme cases, prison sentences.

The legal impact of defending your rights as a creator is you retain those rights, and may collect damages.

Aside from the "fair use" exception , and allowances made for "right of 1st sale" and libraries, archives, etc. copyright law gives the rights owner absolute control over their intellectual property.

Five basic rights are conveyed to the author. They are the ability to control duplication, display, performance, distribution and creation of derivative works.

By law, libraries are specifically exempted from copyright infringement. (see related links for the specific language of the law)
