How long can the heirs of a copyright extend it for? 1 Answers as of November 04, 2010I want to use material from a book that was written at the turn of the last century for a book that I am writing now, but I do not want to violate the copyright. How long can the heirs of a copyright extend it for?

The laws for copyright and copyright extension back then were quite different than they are now. Under the 1909 Act there would have had to be a renewal at 28 years for another 28 years thus they only get a total of 56 years. Under the 1790 Act it was 14 years and then a renewal for another 14 years. Simply stated you don't need any permission to use the material.
