What is the ruling on dealing with copyrights when preparing digital programs and libraries for the blind? Is it necessary to seek permission or cite sources when converting materials for electronic reading, Braille printing, or audio recording, especially if the work is charitable or might become commercial in the future?

Copyright, production, and innovation rights – or intellectual property rights – are financial and moral rights protected for their owner, unless the owner voluntarily relinquishes them. Information published on the internet or in books belongs to its owners, and most websites permit the use of their scholarly materials for copying and downloading solely for personal benefit. If copyright is explicitly reserved, then copying is not permissible except with the owners' permission. If it is not explicitly stated, this indicates permission for use, and it is sufficient to cite the source. However, selling any of this production is not permissible except with the owner's permission.
