Were you ever denied a book by a librarian?

Well, there was this one time that I wanted a book that was in the restricted section, and I didn't have a teacher's note allowing me to go in there, so I just took my invisibility cloak one night and snuck in anyway. The librarian suspected nothing.
- I wasn't even looking for a book. I had slipped into the Webway by complete accident, and then this clown god shows up and makes jokes about library cards, and the walls just keep saying "bazinga". He eventually let us in but by the Emperor that was creepy.

I went to my local, very-small-southern-Bible-Belt-Town library asking for a copy of Children of Lucifer: The Origins of Modern Religious Satanism, which is a dense, scholarly book (extensively researched!, lots of end notes!, published by the Oxford University Press!), and not even remotely sensationalist. I put in a request for an interlibrary loan, because they didn't have a copy in the system that my library is part of; I assumed that it would need to come from a university.
Not unexpectedly, I never received a call, email, text, or anything at all following up on my request. I strongly suspect that they "lost" it.
The book is considerably less expensive now; I think the exchange rate is why it was previously so expensive.

My brother was denied shakespear when he was 10 because it was "above his reading level".

In 3rd or 4th grade I tried to check out Anne Rice's The Servant of the Bones and was denied because "Anne Rice is too mature for someone as young as you". I told the librarian that my parents recommended the book after I read Interview with the Vampire, which I found on my parents' bookshelf after reading Dracula. I was then told that I could bring in a signed permission slip and when I came back with my mom she chewed out the librarian for gatekeeping a book because it has sex in it.
I definitely didn't understand a lot of the sexy parts the way an adult would, but I enjoyed the story and the mythology it built on. My mom was pretty good, folks.

Never. I haven’t seen any snide looks or side eyes, either, and if I can’t find something then the ones I’ve seen (in both red and blue states) have been as helpful as can be, trying to find things in library networks or in other formats (ex: Libby).

Not denied, no. But the librarian wasn’t quite sure what to do when I was checking out The Da Vinci Code at about 11 y/o. At the time I didn’t understand why she looked so surprised/concerned when she asked whether it was for my mom and I said no, but I kind of see her point now. Then again, 11 y/o me loved it.

Yeah. Some dingus put the book I was wanting back the shelf after it was marked reserved by another person, so I couldn't take it that day.
