Prodded by climbing sales for books like Twilight, Borders Group is carving out space in its stores once used to sell music and DVDs for Borders Ink, a section dedicated to graphic novels, fantasy and young-adult titles.

The Wall Street Journal reports that by August the departments will be open in 80 percent to 90 percent of the 513 Borders superstores in the United States. Some shops are now operating in the book chain's home base of Michigan.

Borders Ink already has set up on Facebook, where yesterday it spotlighted Bryan Lee O'Malley's Scott Pilgrim series.

According to the Journal article, the move comes at a time when book retailing is in a slump but sales of YA titles, fantasy and graphic novels are still climbing.
