In the United States, a book is copyright protected for the life of the author plus 70 years after their death. If the work is created by multiple authors, the copyright lasts for 70 years after the death of the last surviving author. For works created by corporate authorship, the copyright lasts 95 years from publication or 120 years from creation, whichever is shorter.
For most normal uses, no, as long as it's properly cited.
Each book has its own copyright information.
Copyright fees in the US range from $30 USD to $220 USD.
Once you have written a book, it is copyright to you. All writers copyright their own books.
Copyright exists as soon as the book is finished and it is not necessary to formally register with the US copyright office before publication.
Copyright laws can protect comic book characters as long as they meet the requirements for copyright protection, such as being original and fixed in a tangible medium. Characters that are sufficiently distinct and unique can be protected by copyright, but individual elements like powers or abilities may not be enough to protect an entire character.

You cannot copyright a book with a future date. Copyright applies automatically as soon as the work is set in "permanent form," which usually means when it is written in draft. Copyright continues until 75 years after the death of the author. No actions are needed to obtain this property right. However, in the US, protecting your copyright in a book can be easier if the copyright statement appears in the front of the book.
