Eh, this one just didn't do it for me. If someone is a collector of objects rather than knowledge, well, that's their fandom. I've heard too much "Quit liking things I don't like!" arguments in fandoms to feel like it's worth getting het up over.
The guardian of the library was quite creepy (though I unfortunately fixated on it as a Beholder and never quite got rid of that image), but the story arc was massively unsatisfying. "Look at this guy! He doesn't lend his books! Haha he got et!" I feel like Endart had enough self-awareness (witness his self-imposed limit on buying new books) that some friendly guidance might have helped him get over his hangups and loosen up enough to be a pretty cool dude, but instead he gets devoured because he didn't immediately read the books he had no idea would be worth reading anyway.
I dunno. It felt like one of those stories one writes as a 12-year-old nerd in which the bullies at your school have horrible things happen to them when the aliens land or whatever; a little too axe-grindy, and a little bit too self-blind in its choice of targets and execution. I mean, don't get me wrong, I read the living hell out of my books, to the point that many of them have fallen apart after the thirtieth or fiftieth reread, but I don't hate on people who buy rare and expensive books because they look nice and/or impressive, any more than I'd hate on some dude for liking football.
EDIT: To clarify, I'm referring to the stories *I* wrote as a self-blind 12-year-old nerd with an axe to grind. :-D
