From the website, with my bolds:
"Teen Read Week started in 1998. This year's theme is Picture It @ your library®, which encourages teens to read graphic novels and other illustrated materials, seek out creative books, or imagine the world through literature, just for the fun of it. Libraries across the world celebrate Teen Read Week with a variety of special events and programs aimed at encouraging teens to read for pleasure and to visit their libraries for free reading materials."
Teen Read Week ran from October 18-22.
