I have recently been working with other state archivists and their staff on the issue of providing online access to primary resources. Many states have been approached by vendors (Ancestry.com, iArchives and Genealogical Society of Utah to name a few) interested in developing a business relationship to provide online access to original documents. The Council of State Archivists created a task force, the Online Content Providers Task Force, to deal with the issues surrounding such relationships. The result is a statement of intent, guidelines and issues to consider while working on any digitization project. You may access the online statement at: www.statearchivists.org
If you have any questions about the statement please contact me directly at the Archives of Michigan.
