Google Books has received an iPhone-friendly version of the site, which can be accessed on your iPhone via books.google.com/m. There are currently 1.5 million public domain books available on the site that can be read in the iPhone’s browser.
The home page lets you search for books or browse by category. I searched for Jules Verne’s Twenty Thousand Leagues Under the Sea and was reading in just a few seconds. The site loads the books a few pages at a time, and there are controls for turning pages or skipping around to different chapters.
If you’re logged in to your Google account, the site will remember where you last left off and will load the correct page the next time you access the site. Reading via Google Books is, however, an online experience, so there’s no support for offline reading…yet.
