Starting this month Barnes & Noble is extending its B&N Recommends program (www.bn.com/recommends), which it launched four years ago for bestselling hardcovers like Mary Ann Shaffer and Annie Barrows’s Guernsey Literary and Potato Peel Pie Society, to include trade paperbacks.

“Trade paperbacks are the format of choice for many of our bookstore customers,” said Patricia Bostelman, v-p of marketing for B & N, “and we’re excited to be able to expand the Recommends program and suggest great titles selected by our knowledgeable and passionate booksellers.”

Each month buyers will choose two paperbacks, either reprints or originals, one in fiction and one in nonfiction, which will be featured in B&N stores across the country. The September selections, on sale today, are: Jeannette Walls’s Half Broke Horses and Sue Monk Kidd’s Traveling With Pomegranates.
