Penguin Group and electronic-book distributor 3M have made a deal with two New York City public library systems — New York Public Library and Brooklyn Public Library — that will return Penguin e-books to library shelves for a one-year pilot.

The pilot, crafted to protect e-book sales, will delay the release of e-books to the libraries for six months after the titles go on sale in stores and online. The e-books will be available under a one-year license.

They will also be available on a number of devices and operating systems—including PCs, iOS (iPhone, iPad, iPod Touch) Nooks and Android devices.

According to an announcement from 3M, Penguin e-books will be sold to all customers using the 3M Cloud Library by the end of the year. In June, when the program was first announced, Penguin said that if the program is successful, it could be rolled out nationwide.

Tim McCall, vice president of online sales and marketing at Penguin, said the company will make all of its titles available—some 15,000 e-books.

Digital Book World also added:

“At the end of the year, Penguin will join HarperCollins and Random House as the three major publishers to allow libraries to purchase all of their e-book list. Hachette and Macmillan are currently engaging in pilot programs to test library e-book lending and Simon & Schuster does not currently make its e-books available to libraries.

Note: Penguin removed all of its e-books from libraries and ended its relationship with digital library distributor OverDrive in February 2012.
