I fell in love with Lulu, a self-publishing tool. For $0.02 per page, one can publish a paperback book. There is also the option of selling the book online. Other options are hardcover books, and ebooks, although I forgot to check what the cost is for those formats. Students and teachers could publish their own writings at very little cost. I know of a student who enjoys writing and illustrating children's stories. What a perfect tool for her!
How I needed Lulu back when I wrote my master thesis --- around the time when the dinosaurs went extinct, before computers and Internet. I still have a bound copy of it, but it was expensive and complicated to get it done. I am totally giddy about this discovery!
