Iowa City librarian Jason Paulios pulls out his smartphone, enters his library-card number and begins downloading an album by local metal band Blizzard at Sea.
"So it's extracting now," he says, eyes on the screen. "It's at about 90 percent."
The download takes about five minutes to complete. Paulios says it's a great way to check out local music: You could be waiting for a concert to start, download an album by the band you're about to see and then listen to it on the way home.
