Google eBookstore launched in December with one hundred participating independent booksellers, but now over 250 bookstores are selling digital books through Google.

The company now counts over 7,000 participating publishers, a 40 percent increase in half a year. In addition, Google Books counted 2.5 million downloads of the eReading app for iOS, Android and Chrome tablets. The 250th bookstore added was Old Harbor Books in Alaska.

Old Harbor Books co-founder Don Muller blogged the milestone: “Based in Sitka, Alaska, Old Harbor Books was opened 35 years ago last week by a group of devoted book lovers including myself. Old Harbor is an independent bookstore specializing in Alaskana, Native American and Alaska Native, children’s, ecology, travel, natural history, philosophy and, of course, nautical books. And starting today, we also sell Google eBooks on our website … In a town with a population of less than 9,000, we’re proud to provide personal service to the readers and explorers who visit our store.”
