Speaking of banned books:
I was refused access to books several times.
1- in second grade I was reading my way through the Wizard of Oz series (I loved the illustrations, too) and when I tried to check out the fourth or fifth of the series, the volunteer running our tiny public library in our tiny town took it away from me. This is a fourth grade book. If YOU take it, you'll be denying someone who has the right to read it.
2. Elementary schools didn't have school libraries or librarians in the 1940s, so no access there.
3. In fifth grade, my father had a meeting of his astronomy club (only adult men attending) in the public library, so he took be along so that I could browse the children's department and find books for me to read while I waited for him. But the children's librarian didn't work that evening so THE CHILDREN'S DEPARTMENT WAS CLOSED. The librarian (or circulation person) that was there grudgingly let me read a magazine, but only one that she picked out, not the more interesting one that I wanted to read.
