Get the books here in any of 4 formats for just $10 each!
The AZW3, EPUB, MOBI, and PDF formats are only available here. If you prefer the very attractive Kindle Textbook format for any of these books, you may get that at Amazon.com. The Kindle Textbook version can be read in the Kindle app for all Microsoft (Windows), Apple (Mac, iPhone, iPad), and Google (Android) devices. Unfortunately, Kindle textbooks are supported by only a limited number of Amazon (Kindle) devices. Currently, no other Kindle format yields a satisfactory result due to conversion problems relating to Amazon’s lack of support for the Bengali language.
NOTE: For use on an Android or iOS device, the ePub file will probably be best; however, the PDF file offers easier cross-platform performance and a higher guarantee of consistent visual quality. (The MOBI format is a last resort for those who still use a device so old that nothing else works.) If you are not satisfied with your reading experience, the free Gitden Reader might make an improvement. It is available for download at the Google Play Store (Android) and the Apple App Store (iOS).
