Not so much "an eBook" as a huge library of eBooks, this might just be the best application about Buddhism on the App Store!
This is the entire offline version of John Bullitt's widely recognized and highly recommended Access to Insight (www.accesstoinsight.org) web site, a massive compilation of material about Theravada Buddhism and Buddhism in general.
Herein are contained over 1,000 *actual suttas* (skt: 'sutras') from the Tipitaka (body of Buddhist canonical texts) translated into contemporary English with scholarly rigor and precision by recognized subject domain experts. Suttas are not simply modern essays and interpretations; they are actual written discourses historically attributed to Siddhartha Gotama, the Buddha, who founded Buddhism nearly 2,500 years ago.
A massive and thorough collection of essays by world-renound monks and scholars on the subjects of Buddhist philosophy, meditation, and practice is also included.
This is high quality material that is suitable reading for personal interest or academic study. Much of the material has also been published in printed form.
To aid the reader, indexes are available by subject, author, title, sutta title, proper name of historical figure, simile/metaphor, and even traditional numerical association.
Usability Features of the Software
The reader works much like a web browser. Double tap on the screen to hide or show the toolbar and status bar. Landscape and portrait modes are supported, as are bookmarks which save the current scroll position of the current page.
Network access not required!
Except for the search and audio features, network access is not required. The full text is stored locally on your device.
Many of the sutta translations also link to iPhone accessible online audio readings on suttareadings.net.
Excerpts from "What is Access to Insight?" by site owner John T. Bullitt:
"Access to Insight is an Internet website dedicated to providing accurate, reliable, and useful information concerning the practice and study of Theravada Buddhism, as it has been handed down to us through both the written word of the Pali canon and the living example of the Sangha."
"The readings assembled here represent just a selection of the Buddha's teachings. These are the ones that, over the years, I've personally found to be helpful in deepening an understanding of Dhamma practice. This collection is not meant to be an exhaustive archive of Theravada Buddhist texts."
"Everything available at Access to Insight is offered in full cooperation with the authors, translators, and publishers concerned, with the clear understanding that none of it is to be sold. Please help yourself to whatever you find useful."
