It depends on the county. Some have set up their own imaging systems but these seem to be rare. In Lubbock if they county clerk had not been stopped she was about to sign a contract with the imaging company to pay them 3/4 of a million over the next 3 years. You can make an opens records request for any contract the county has entered into. While you are at it, you might want to make an open records request as to who they have sold to in bulk and for fees were paid.
