Only if the copyright is not part of the copyright registration that is copyrighted in the publication of the author's registration.

There is no "set amount" of a copyrighted work that can be used without infringing on the author's copyright Technically an email is considered a "literary work" and unless the use would fall under the "fair use" exception it can paraphrased but cannot be directly quoted without permission from the original author.

The answer to it is "No Copyright" The Kama Sutra, as well as other Sutras, are not, of them-selves copyrighted and are public domain. This is because, basically, there is no ownership that has coyrighted them as they were written long ago. The same may be said of the art-work accompanying the Sutra. However, if a new author was to write a work that included the Sutra, he or she could copyright their work and any new illustrations created for their work.
The entire novel is copyrighted. While one cannot technically copyright a title, the book is a copyrighted work. The holder can bring suit against anyone that violates their rights.
The only way a work created by you can become 'not' copyrighted, is if you've voluntarily given up those rights.
