O’Reilly & Associates, a leading publisher of books on computer technologies, announced it will adopt the Founders’ Copyright from the Creative Commons project, “that allows copyright holders to voluntarily release their works to the public after the period envisioned in the original 1790 US copyright law–14 years, with the option of one 14-year extension.” The Sony Bono Copyright Term Extension Act of 1998 extended the duration of copyright, on works published on or after 1978, from 50 years to 70 years.
