The software is free to download. Once you have uploaded your book you can order as many copies as you want. Prices begin as little as £6.95 for a 40 page soft cover. You can also design in a variety of sizes, in both hardcover with dust jacket and soft cover.

I have uploaded a book of my friends Dermot and Anne's kids – Grace, Seamus and Kate.
The other site to have a look at is Lulu.com/uk. They perform a smilar function, but you can also do black and white perfectly bound books with just text from as little as £3.80
