I have used slideshare to promote new books on my library xanga.
Students feedback: "Its easier and more convenient to view the information of new books than downloading the word file. ", "Its interesting and new experience."
My evaluation: Its attractive and good method to promote new books. However, it seems there is a problems for slideshare to convert Chinese fonts. And it takes a lot of time for me to amend the powerpoint for reduceing the errors.
