Banned Books Week is an annual event celebrating the freedom to read. Typically 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 — in shared support of the freedom to seek and express ideas, even those some consider unorthodox or unpopular.

To continue to raise awareness about the harms of censorship and the freedom to read, the American Library Association Office for Intellectual Freedom publishes an annual list of the Top Ten Most Challenged Books, using information from public challenges reported in the media, as well as censorship reports submitted to the office.

Out of 323 challenges recorded by the Office for Intellectual Freedom, the top ten most challenged books for 2016 were:

1. This One Summer written by Mariko Tamaki and illustrated by Jillian Tamaki
   Reasons: challenged because it includes LGBT characters, drug use and profanity, and it was considered sexually explicit with mature themes
2. Drama written and illustrated by Raina Telgemeier
   Reasons: challenged because it includes LGBT characters, was deemed sexually explicit, and was considered to have an offensive political viewpoint
