Only someone who accepts individualism as the highest good would be so confident that there is
an obvious qualitative difference between the «freely chosen» decision to die made by a person facing a terminal illness and a decision made by a physically healthy but mentally tormented individual.
As such, I don't think the ProCD case applies in my situation due to the
qualitative differences between licensing CD - ROMs with vast amounts of information that has been compiled and which has value added search features added to it versus the «sale» of single copies of public domain sheet music (however, a library that creates and licenses for sale a CD - ROM with hundreds of individual pieces of public domain sheet music might be protected by the principles in ProCD since a court might recognize and protect the library's investment of time and money in creating the CD - ROM, but even in that situation, if the library is not otherwise adding value - added information above and beyond the public domain content, it is not
obvious that ProCD applies).
