At Bookemon, you can create an online book for free that can be shared and also have the option to purchase a printed version.
What really makes it attractive to me, though, is that you can use any of its templates for a book and just upload a Word or PDF document that will automatically be inserted into the book. In other words, a student who is familiar with Word can write a “book” — including images he/she took or ones they grabbed off the Web (that are copyright-friendly, of course); upload it to Bookemon; and within minutes have an online presentation that looks very much like a virtual book.
I really like applications that let students use something they are very familiar with and then convert it into something a lot neater. Students just with the knowledge of typing and copy and pasting can quickly create a piece of writing that looks a lot more attractive and can be shared.
I’m adding Bookemon to The Best Places Where Students Can Write Online.
