I don't care how "noble" her "reasons" will turn out to be, she is still an asshole.
Also, a public library main goal is providing access to books for people that couldn't get them otherwise: as such, the children and Y.A. sections are probably the most important ones, since they are the ones with the least means to buy books. Also, also, you could find the "classics" in any other library in the area, so focusing only on them goes directly against the objective of providing the widest catalogue on a limited budget...
