Quick Facts About Public Domain Works
Here are some quick facts that you should know about the copyright laws applying to the public domain. Note: These laws apply to works published in the US. For unpublished works and for works published outside the US, see the resources listed later on. · Any works published (with or without copyright) before 1923 are in the public domain. · Any works copyrighted in 1923 or later (with their copyrights renewed in time) will stay OUT of the public domain till 2018 or longer. This is due to a 20-year copyright extension enacted in the US in 1998.
Usually you can check on the book itself the copyright date, and if a copyright is renewed, that date is also placed on the book. · Certain works copyrighted in 1923 or later may have already entered the public domain because of certain legal constraints. The following types of works o Works published in the US before 1989 without proper copyright notice and o Works published in the US before 1964 whose copyrights were not renewed · Works from 1923 or later that were originally published in countries outside the US may still be copyrighted regardless of whether they were printed with proper notice or renewed. · Works that were never registered for copyright prior to 1978, and were never published prior to 2003, are now in the Public Domain in the US if: o The author(s) died more than 70 years ago before the most recent New Year’s Day.
