The issue of copyrighted work needs to be tightened so that if offers greater to protection to the creator of the original work, that is the author, composer or designer during their life time and only 25 years after their death.
However, work which is wholly or in part based on the work on an original work during the original copyright holders period of copyright will be protected for a period of 50 years only. Work based on an original work after the original copyright holders period of copyright has expired is not protected by copyright as the original creater directly does not benefit.
Work which is based on work which is wholly or in part based on an original work is not protected by copyright during the lifetime of the original creator or at anytime in the future.
Once the period of copyright has expired, the work must be made available to the general public for free or for a nominal charge to cover reproduction.
Why is this idea important?
The general public are being charged for work which has been outside its copyright period for many years. For example the musical works of Beethoven, Bach, Mozart, Handle, Brahms, Chopin, Scarlatti,Schumann, Vivaldi . The works of authors such as the Brothers Grimm, Lewis Carroll, Johanna Sypri.
Currently anyone can take a non copyrighted work, publish it and then claim copyright over the non original work. This approach does not encourage the publishing industry to actively seek new authors, composers or creators of original works; rather they exploit the work of dead creators who require no payment.
