Unfortunately, Earl, Iowa is a bit more restrictive in the availability of their lists. There is an IAGEN-L, however, it's restricted to volunteers and county coordinators. For any sharing of information, or queries, they prefer you use their county web pages and archives on-line. I own a few books and other data about western Iowa genealogy, so if there is anything that I can help you with, just e-mail me directly......particularly if it pertains to Pottawattamie County, or to Harrison County.
