She only got super rinsed if you only count the labour value of the books being copied. Free unlimited access to those books forever is priceless.
Yeah, I recall that part of what made voting for the Library of Mournings so popular back then is that since we were trading ithilmar (a military resource), you said that magical books were on the table. I suppose the only other way we'd have gotten them would have been by directly offering our help in putting down some gribblies here and there, in a meaningful way? Maybe getting a bunch of other wizards involved to help out? Who knows.
And besides the magical books, while we had access to most of the mundane books, that's because the Library of Mournings works extremely differently from human libraries, which are very careful about who they give copying rights to for a variety of reasons. One day Laurelorn elves will find out be and shocked that humans would so jealously guard their own knowledge, meager though it is. Some because of a fear of that knowledge being misused, some because other people not having
your knowledge makes your books more prestigious. Competition can breed ruthlessness, in the end.
And, of course, the Old Ones scrolls are effectively priceless entirely on their own, even if they're currently indecipherable.
Speaking of priceless books, I'm still looking forward to the Karak Vlag books. It will not only be fascinating to find out what sort of nonsense the Vlagians had to endure and their doomed attempts at trying magic, but there's probably some things in there too about the actual writers of the books, the wizards of the Fire Spire.
Some of those wizards might have been the predecessors of the Colleges. Who knows what we may find out...
