Since 1982, the American Library Association (ALA) says over 11,300 books have been "challenged," by people wanting them removed or restricted in libraries, bookstores, and schools.

It's something they wants everyone to know about, so they made it official, by calling the week of September 25th "Banned Books Week."

"No literature should be banned," said Richard Reyes-Gavilan.

"At the DC Public Library we've got our own spin on Banned Books Week and we call it 'UNCENSORED.'"

Reyes-Gavilan is the Executive Director of the DC Public Library. Under his leadership, the library has already started getting the word out about banned book - by actually hiding books.

Across the city, books that have been challenged or banned are hidden in local business. The cover of each book is replaced with a black sleeve and the words people used to try and get them restricted.

The library wants regular people to go looking for the books.

If you find one, grab it, take a picture, post it to social media using the hashtag #UNCENSOREDDC, and you could win tickets to a cocktail party on September 30.

Since it's a cocktail party, you have to be 21 to win - but the party isn't really the point.

The goal, according to Reyes-Gavilan, is to raise awareness, protect freedom of speech, and make sure every person has full access to information.

This year all of the books featured in the scavenger hunt are related to diversity.

The DC Public Library says it's a theme they chose to "celebrate literature written by diverse writers that has been been banned or challenged, as well as explore why diverse books are being disproportionately singled out in the first place."
