I am not a lawyer but what I ascertain from this if your country of residence is a member of the Berne convention you can apply for a copywrite. The Netherlands is a member. Here is some info for you to look over. Should not be to hard. You can go to the following website to copywrite you material.

The United States became a member of the Berne Convention on March 1, 1989. It has been a member of the UCC since September 16, 1955. Generally, the works of an author who is a national or domiciliary of a country that is a member of these treaties or works first published in a member country or published within 30 days of first publication in a Berne Convention country can claim protection under the treaties. There are no formal requirements in the Berne Convention. Under the UCC, any formality in a national law can be satisfied by the use of a notice of copyright in the form and position specified in the UCC. A UCC notice should consist of the symbol © (C in a circle) accompanied by the year of first publication and the name of the copyright proprietor (example: © 2006 John Doe). This notice must be placed in such a manner and location as to give reasonable notice of the claim to copyright. Since the Berne Convention prohibits formal requirements that affect the “exercise and enjoyment” of the copyright, the United States changed its law on March 1, 1989, to make the use of a copyright notice optional. U.S. law, however, still provides certain advantages for use of a copyright notice; for example, the use of a copyright notice can defeat a defense of “innocent infringement.”
