''Publication'' is the distribution of copies or phonorecords of a work to the public by sale or other transfer of ownership, or by rental, lease, or lending. The offering to distribute copies or phonorecords to a group of persons for purposes of further distribution, public performance, or public display, constitutes publication. A public performance or display of a work does not of itself constitute publication. (17 USC Sec. 101)

(17 USC Sec. 101)

Copyright for items that have been created, but never published, consists of the life of the author, plus 70 years. However, the earliest ANY item which has been created and not published before 1978 goes into the public domain is 12/31/2002. If the item is published BEFORE 12/31/2002, copyright is automatically extended to 12/31/2047.

Items published before 1963 have a copyright of 28 years which could be renewed for 47 years. Usually, one must use the services of the United States Copyright Office to see if an item's copyright was renewed. If an item published between 1923 and 1963 did have its copyright renewed it has a 75 year duration of copyright and this is not yet in the public domain (1923 + 75 years = 1998).

Items published before 1963 have a copyright of 28 years which could be renewed for 47 years. Usually, one must use the services of the United States Copyright Office to see if an item's copyright was renewed. If an item published between 1923 and 1963 did NOT have its copyright renewed it has a 28 year duration of copyright and thus is in the public domain (1963 + 28 years = 1991).

If the copyright notice was omitted or defective on published copies distributed between January 1, 1978 and March 1, 1989, the item may still NOT be in the public domain. If the publisher took prescribed preventive measures, the item may indeed be under copyright.
Defective copyright notice before January 1, 1978 generally put an item in the public domain once it was published.
