To be fair, it also sounds like an unfair comparison. A century vs a decade. And how many duplicates in the out of copyright works? The public doesn&#x27;t really benefit from 100 different editions of Sherlock Holmes&#x27;s early adventures that differ only in how the cover is rendered and whether the &quot;publisher&quot; charges 99 cents or a 1.03 dollars.<p>Edit: Oops, late 1800s vs 1990s is not add unbalanced as a century vs a decade. The dupes are still a big issue if he didn&#x27;t handle those.
