The following information is for those who are concerned about the nature of the copyright of maps placed in the USGenWeb Archives.
We claim no copyright of scans of original pre-1922 maps which are in the public domain. We require that all contributions be offered to us on a permanent basis. Please note, permanent basis does not mean exclusive basis. Additionally, we are not able to accept actual assignment of copyright. The copyright holders should remain free to use the map anywhere that they deemed proper. We do not want to limit the submitters' ability to publish and/or sell their own work; we simply offer an organized, permanent place to make the work available to Internet researchers - and with free access to the files. We want to offer people an opportunity to share their work with others, in a central location on the Internet to provide that permanency.
