Audio Duplication Policy:
When an audio recording can be legally duplicated, without risk of damage to the original, we make copies available upon request. The National Park Service does not presume that all Edison recordings are in the public domain. Under certain conditions specified in the law, the National Park Service is allowed to furnish a reproduction of the audio recording if it does not infringe upon the legal rights of any individual, group, or corporation. These “fair-use” conditions include:
Certain items in the collection are extremely fragile or are otherwise inaccessible, and therefore cannot be duplicated. The National Park Service will refuse a duplication order if fulfillment is judged to be in violation of “fair-use” provisions of the copyright law, or if the items are judged too fragile or problematic to reformat in a professional manner.
Did You Know?
Clarence Madison Dally an employee of Thomas Edison at his West Orange research labs volunteered to work on the newly discovered x-rays. Using a fluoroscope, made of a fluoride gas filled light and two pieces of cardboard to focus the x-rays, Dally would expose himself to high concentrations of radiation eventually leading to radiation poisoning. After Dally’s death when Edison was asked about x-rays he would respond with “Don’t ask me about x-rays. I am afraid of them.”
