This information is primarily collected for statistical analysis and technical improvements to the site. The National Archives uses software programs to create summary statistics, which may be used for such purposes as assessing what information is of most and least interest, determining technical design specifications, and identifying system performance or problem areas. In certain circumstances, however, we may take additional steps to identify you based on this information and we may share this information, including your identity, with other government agencies. The information we collect for statistical analysis and technical improvements is maintained indefinitely. Although questions, comments, and other communications that we receive generally are not retained as permanent records, please note that it is possible that any mail - electronic or paper - that we or any other Federal agency receive could be permanently retained by the agency, if the mail is part of a group of records determined to have permanent historical value.
