There are many site that provide free forms for us to download. One from the Western Wayne County Michigan Genealogy Society recently came to my attention. It offers not only the usual census forms, pedigree charts, etc., but also some some that you do not often see. Examples of those are forms for Michigan death records, Ohio vital records, WWI draft cards, and many others.
The forms are nicely categorized and all can be downloaded in pdf format. Check out the site at: http://www.rootsweb.ancestry.com/~miwwcgs/forms_and_charts.htm
