It is banned books week. For those who haven’t heard of it, this is a celebration of the freedom to read what we want. On this week booksellers, librarians, publishers, teachers and writers band together to publicize the many books that have been, at some point or another, challenged and taken off bookshelves. Read a banned book this week. Advocate for one. Buy one or check it out of the library. And support those who, like the students in Colorado's Jefferson County near Denver have seen fit to do in the past couple of days — and Chicano and Latino writers did after the Tucson Unified School District pulled Mexican-American history and literature from school bookshelves — refuse to allow books and U.S. history to be sanitized and expunged.
