The more work the kids do on the yearbook, the better received it is and the easier it is to sell.

online book is really, really easy and kid-friendly. It's called Yearbook Avenue and requires no special software or anything extra.
They also give you three levels of passwords - one for the advisor which overrides all other pws, the editors and the staff. This means the kids can work from home.
The neatest thing is that parents and other community people can post their digital photos to a community site where you can, as advisor, choose to upload to the yearbook's photo library for the students to include (or not) on their pages. Saved my rear last year when one of my non-yearbook students erased the memory stick with all our volleyball pictures on it before the staffer had a chance to upload them to the computer. All the parents who had taken pictures uploaded them to the community site and our volleyball team's pages were saved!
Lifetouch
has the capability of doing your yearbook online. I am not sure how it works because our faculty advisor gave me the evil eye along with the death ray stare when I mentioned it to him. He is a paper only kinda guy. Anyway...you might want to check it out.
