>I came across this site recently. It is called Booklet Creator and can be found at http://bookletcreator.com/
Booklet creator will take any PDF document that you upload to it and convert it to a multipage booklet. You can select the number of pages and size.
This could be a great resource for teachers and PTA's that want to take documents and turn them into booklets for parents.
You can convert documents to PDF format by using adobe acrobat. If you do not have acrobat you can use PRIMO PDF. It is free. http://primopdf.com
