Gay Books
"King and King" is a picture book for little kids. Kids and parents look for picture books in the picture book section. The only way kids from LGBT families are going to find these books is if they especially ask for them, outing themselves in what is clearly a not tolerant community. This isn't fair.
Also, when the books don't circulate because nobody knows to look for them in these weird sections, I bet they use the low circulation statistic to justify not buying additional ones.
