One of the biggest shocks for me when I first enrolled in college was the insane cost of textbooks.
In addition, they do tend to be a bit cheaper than physical books.
Electronic textbooks offer a bunch of cool feature that real books just can’t match up with.
To me, the most crucial one of these is the ability to search in the document.
Ecampus.com’s eTextbook Store
Ecampus’s eTextbook store claims to have over 100,000 eTextbooks available.
Their ebooks are rentals, so you have full access to the book for a period of 180 days.
All electronic textbooks available on their site can also be read on the iPhone, iPad and iPod Touch.
They have a full search function that allows searching by author, ISBN, title, and keyword.
CourseSmart
CourseSmart offers the same basic search functions as the previous site.
They allow you to get access to 3 chapters from up to 5 books offline at a time.
CourseSmart allows you to preview and get a trial of any book available in their store.
They also offer mobile reading on all Apple devices.
CourseSmart had the book, but it was the earlier edition.
Conclusion
eTextbooks are still a relatively new thing.
