Here is a web site to get all your books and poems that you wrote into a published book for a very low cost. blurb.com. I've seen one of the books and they are very classy. Elijah loves to write poems and my grandmother published poems in her local paper during her younger years. This is something I would like to do with her poems.
You can also go to lulu.com - that is where I got mine published. They are an afiliate with the national write a book in a month program (I can't remember the website - something line namuro.com but that is not it) that was discussed in Practical Homeschooling last year I think. November is the month this event usually takes place in.
