From the press release...

Borrowing eBooks and audiobooks from the library just got a whole lot easier for users of the NOOK HD, NOOK HD+, NOOK Tablet™ and NOOK Color™.

Last week, Barnes & Noble added the OverDrive Media Console app to the NOOK Apps™ storefront. This NOOK app enables users to wirelessly borrow eBooks and MP3 audiobooks from the library.

All NOOK devices, including NOOK 1st Edition, NOOK Simple Touch and

NOOK Simple Touch with GlowLight, have always enabled users to read eBooks borrowed from libraries and schools, but the process required sideloading the files from a computer using Adobe Digital Editions and a USB cable. Now users of NOOK HD, NOOK HD+, NOOK Tablet and NOOK Color can borrow eBooks and audiobooks wirelessly using the OverDrive app.

Users can visit the NOOK Apps storefront to install the free OverDrive Media Console (OMC) app. The app enables users to locate a library or school nearby, browse or search their eBook and MP3 audiobook collection and, after entering a valid library card or school ID,  check out and download the title for a lending period of one to three weeks (depending on the library or school's policies). At the end of the lending period, the title simply expires.
