Copyright

A copyright is a set of exclusive right granted by a state to the creator of an original work or their assignee for a limited period of time in exchange for public disclosure of the work.This includes the right to copy, distribute and adapt the work. In most jurisdictions copyright arises upon fixation and does not need to be registered.Copyright owners have the exclusive statutory right to exercise control over copying and other exploitation of the works for a specific period of time, after which the work is said to enter the public domain.

Uses covered under limitations and exceptions to copyright , such as fair use, do not require permission from the copyright owner.All other uses require permission. Copyright owners can license or permanently transfer or assign their exclusive rights to others.

Initially copyright law applied to only the copying of books.Over time other uses such as translations and derivative work were made subject to copyright. Copyright now covers a wide range of works, including, 

 maps,sheet music dramatic works,paintings,photographs,architectural drawings,sound recordings,motion pictures and computer programs.The British Statute of Anne 1709, full title "An Act for the Encouragement of Learning, by vesting the Copies of Printed Books in the Authors or purchasers of such Copies, during the Times therein mentioned", was the first copyright statute. Today copyright laws are partially standardized through international and regional agreements such as the Berne Convention and the WIPO Copyright Treaty.. Although there are consistencies among nations' copyright laws, each jurisdiction has separate and distinct laws and regulations covering copyright. National copyright laws on licensing, transfer and assignment of copyright still vary greatly between countries and copyrighted works are licensed on a territorial basis. Some jurisdictions also recognize moral rights of creators, such as the right to be credited for the work.
