Google Play Books has just released a new update today for iOS and Android that will greatly enhance its relevance. Google now allows users to upload their own ebooks in EPUB or PDF format into Google Drive or via their new Uploading Tool. Once the books are stored in the cloud, you can read your books within the main Google Books app.
Google has adopted a new strategy to open up its book ecosystem to users who have their own ebooks (without DRM) to read. You can download books from anywhere on the internet and upload them to your Google account. You can then make notes, annotations, and sync all of your data. This is very useful to people who have adopted smartphones and tablets in their lifestyle.
The new Google Play Books app is available via the Good e-Reader APP store and iTunes.
