In my country it is not.
One can migrate content protected by Copyright as stated in the “Código do Direito de Autor e dos Direitos Conexos” (
https://ciist.ist.utl.pt/docs_da/cod...epublicado.pdf), point 2-a) of the 75th article who says in it’s end (roughly translated):
“(…)as well reproduction by all means done by individual person, for his own private use and without any direct or indirect commercial proposes.”
Of course it says in the next article (76) that a fair retribution must be paid to the owner of the Copyright, but that’s another story…
Instead, “freeing” of DRM is forbidden - articles 217 and following of the same document - where it states that it’s punished by law to break any protection set in a protected document, as is teaching how to do it, selling or buying tools to do it, etc… etc… etc…
So, and even being time consuming, how is the experience of the ones who deal with DRM and/or not finding content in electronic format, choose to migrate pBooks they own to eBooks and why they have chosen it?
