Agreeing with the article, I'd like to add another concern. I help prepare candidates for Holy Orders largely with materials mailed or from the Web. There are useful books long out of print, but still protected by copyright,available only occasionally from rare book dealers. I'd like to be able to scan some of these and provide them to candidates.
Seems to me a reasonable book copyright limit might be some number of years after the book goes out of print and is no longer sold.
Thus the author and publisher would not loose
revenue, but the books would be widely available.
I could even live with a modest royalty policy
for electronic copies of out of print books.
