USGenWeb will not tolerate any copyright violations. Lookup requests should be limited to one name, or perhaps two if it is a married couple. Information given will be minimal, for example, if it is a cemetery lookup, the information will be the name of the cemetery and dates on the headstone. Please do not ask for "everyone with X surname" or an entire family group, or for hardcopies to be mailed; the volunteers have been asked not to comply with such requests. 
Our lookups will extend to searching the book to determine if the book would be helpful to you in your research. Should the book prove useful, we can provide the authors address and ordering information. The GenWeb Project will endeavor to get a WRITTEN statement from each copyright holder which stipulates which books may be used for lookups. If you request a lookup, don't forget to thank your volunteer for their time.
