Genealogists will be quite aware of the records produced that list names, addresses and vital demographic material. The U.S. Census Bureau, not the National Archives, conducts the census. However, the National Archives will be storing the records for use by future generations. Storing everything will require more storage warehouses to be built at taxpayer expense. Keeping every scrap of paper is simply not practical.
Someone has to make a decision as to what to keep and what to throw away.
The National Archives is inviting public comments in order to help in that decision process. Genealogy societies are especially invited to comment.
