In a classroom, students could use this tool to research as they would in a library. Instead of having to borrow out books, students can download their books and view them at home. Like Wikipedia, students would have to be aware of the validity of the information contained within the ebooks that they choose for their research.
There is a huge selection of ebooks available for viewing at this site. When I searched "ICT", an ebook called 'ICT and a person with Special Needs' came up. This ebook contains how a person with special needs uses ICT to help her study while she is at school.
My E Book - another useful tool in a contemporary classroom!
