PowerByHand, a developer of wireless content and solutions, and palmOne have agreed to launch an online eBook store.

The palmOne eBook store will include content from PowerByHand’s eReader.com with some 13,000 titles. Among them are many best-sellers.

Most palmOne devices include PowerByHand’s eReader software.

The Open eBook Forum reported recently that 421,995 eBooks were sold in the first quarter of this year, up from 299,440 a year earlier.

“We are committed to providing our customers with a rich content selection for their palmOne devices, including access to the widest selection of eBooks available,” said John Hartnett, a vice president at palmOne, in a statement. “PowerByHand’s eReader.com is the leader in the eBook industry, and choosing their catalog for our store gives palmOne customers the ability to enhance their device experience and enjoy the mobility and flexibility that electronic reading provides.”
