From 3M:

The 3M Cloud Library App is now available in Barnes & Noble’s NOOK Apps store, making it easier for owners of NOOK tablets to borrow eBooks from local libraries. Anyone with a NOOK HD, NOOK HD+, NOOK Tablet or NOOK Color can download the 3M Cloud Library App directly from the NOOK Apps storefront, and then transfer digital content wirelessly to their device without having to physically connect to a computer.

Users can now opt to browse only titles that are immediately available for check out, eliminating unnecessary time spent perusing books that are currently unavailable – a capability offered for library-based lending exclusively by 3M Cloud Library.
