Penguin and Overdrive make borrowing library ebooks on Kindle easier

A couple days after Penguin made its ebooks available to libraries again through digital distributor Overdrive, the company has also eased up on Kindle (s AMZN) book borrowing. Overdrive and Penguin announced Friday that users will be able to send Penguin library ebooks wirelessly to their Kindles rather than side-loading them via USB. This means users will be sent to Amazon’s website after they borrow an ebook on Overdrive.

Ebooks now make up 33 percent of Penguin’s US revenue
Ebooks accounted for 33 percent of Penguin’s U.S. revenue in the first half of 2013, parent company Pearson reported Friday, up from 31 percent this time last year. Worldwide, ebooks made up 21 percent of Penguin’s revenue, up from 19 percent last year. This is the last time we’ll see earnings from Penguin as a separate publisher, as it is merging with Random House.
