It's National Banned Book Week!

from the web site:

Banned Books Week is an annual event celebrating the freedom to read. Held during the last week of September, it highlights the value of free and open access to information. Banned Books Week brings together the entire book community –- librarians, booksellers, publishers, journalists, teachers, and readers of all types –- in shared support of the freedom to seek and to express ideas, even those some consider unorthodox or unpopular.
Banned Books Week was launched in 1982 in response to a sudden surge in the number of challenges to books in schools, bookstores and libraries. More than 11,300 books have been challenged since 1982 according to the American Library Association. There were 307 challenges reported to the Office of Intellectual Freedom in 2013, and many more go unreported. The 10 most challenged titles of 2013 were:

1. Captain Underpants (series), by Dav Pilkey

By focusing on efforts across the country to remove or restrict access to books, Banned Books Week draws national attention to the harms of censorship. Check out the frequently challenged books section to explore the issues and controversies around book challenges and book banning. The books featured during Banned Books Week have all been targeted with removal or restrictions in libraries and schools. While books have been and continue to be banned, part of the Banned Books Week celebration is the fact that, in a majority of cases, the books have remained available. This happens only thanks to the efforts of librarians, teachers, students, and community members who stand up and speak out for the freedom to read.

Banned Books Week is sponsored by the American Booksellers Association; American Booksellers Foundation for Free Expression; the American Library Association; American Society of Journalists and Authors; Association of American Publishers; Comic Book Legal Defense Fund; the Freedom to Read Foundation; National Coalition Against Censorship; National Council of Teachers of English; National Association of College Stores; PEN American Center and and Project Censored.  It is endorsed by the Center for the Book in the Library of Congress.
