Libraries are usually very well fundd with trust funds from peole who gave them a lot of money years and years ago.
In my town the trustees are on the ballot.
we used to also have a hospital, funded by the old family (that is gone now) but all of that was looted off in the 1980s and 1990s.
and if you go to the Library you get that look of 'why are you in our library'
it's really a limited hang place.
must be some money there.
anyway, ya, libaries are often there just to hide money from taxation.
and then they buy books from a list, and then toss them out after a short time.
they don't keep the books.
many libarary books end up very quickloy as 'ex libres' online, and so ya, it's a place for trust funds to be looted.
and as is typical, like with hospitals and say, certain rich-people vanity churches (like the . . . . . .. ) (i don't give the name) they are often taken over and the property becomes the limited hang out of political people, especially marxists, unionists, and other miscreants of connected power.
