Ok nothing to do with fma but why do school libaries not carry manga

I know what bạn mean. My highschool has only a few mainly Bleach and Naruto.
I do know that in Middleschool it was because some of the manga has bad content (the whole blood, violence, gore, and smutty crap) so most of the sách have to be review before being entered in.

well mine carries fma actually but yeah i get what bạn mean

Considering I assume the fact that thư viện sách come from the schools funding I don't think they buy them with it..they just buy regular book mine probably does it to enforce đọc regular books..rather than manga..why I don't know.

Probably because it's not "educational"
