Hi,
 
We have several copyright issues on our family, what with dad's works in 36 languages now, and requests for something else to be published or translated or what not. We have to use, for the most part, the Portuguese laws, and the main difference now, that the Library has been donated to the Portuguese Government (or something like it), for the National Archives, is that a lot of people are skittish to want to publish a few things, since they have to deal with a bureaucracy that is pathetic, boring, slow, and stupid and STILL uses "papelinhos" (small pieces of paper), not for their bums, but for legal reasons!
 
Copyrights, either way you look at it, is a headache, and in some cases, does not even protect the artist/writer/musician and the like properly, because the whole thing is generally written, mostly for WRITERS ... not any other artistic endeavor. It is only in the last part of the 20th century that this changed so that something like song lyrics and melodies were now also included, but the copyright acts were not exactly rectified to discuss music very well, and it is now a joke about who can hear the best, and has the most money to make sure you can not enter the music "business". ... so to speak! Unless you are playing their stuff and making money for them!
 
All in all ... welcome to the 21st century ... and with folks like tlw and others posting here to derail you, because they wouldn't know the truth from the crap, in their comments!
