Overview#Copyright is a legal right created by the law of a country that grants the creator of an original work exclusive rights for its use and distribution.
Copyrights are a form of Intellectual Property Rights.
A major limitation on copyright is that Copyright protects only the original expression of ideas, and not the underlying ideas themselves.year to include in a copyright notice is the year of first publication of the work. First publication is when the work is made available to the public without restriction. This includes selling a book or leaving free copies of it in a public place or posting content on your blog. Publication does not include, for example, circulating copies internally to co-workers.
New versions or editions of works should contain the publication date of the new version or edition. For constantly evolving websites and blogs that contain works published over several years, the notice may include a range of years (e.g., 2009–2018), starting from the date of the oldest published elements and ending with the date of the newest published elements.
Copyright Notice is not mandatory#Copyright notice is not mandatory in most countries. Notice is not mandatory in the United States or in Canada. Specifically, Copyright is not required in Berne Copyright Treaty countries. In these countries, use of the Copyright notice and symbol is still useful and is a good idea. In these situations, the purpose of the Copyright notice is to educate others or to remind others that Copyright exists in your work and to respect that Copyright.
Some mistakenly think that the lack of a Copyright notice means that the work is in the Public Domain or free to use without obtaining permission from the Copyright holder.
