This literary or artistic work is in the public domain in Malaysia because its term of copyright has expired.
The Malaysian Copyright Act 1987 applies to works first published in Malaysia. The periods of copyright are as follows:
For literary, musical or artistic works, copyright subsists for 50 years after the death of the author. Copyright for unpublished works subsists for 50 years after the publication. For anonymous or pseudonymous works copyright subsists for 50 years after publication unless the author is made known.
For films and sound recordings, copyright subsists for 50 years after publication. For unpublished sound recordings, copyright subsists for 50 years after the fixation. For broadcasts, copyright subsists for 50 years after the broadcast is first made.
Works by the government, governmental organisations and international organisations are subject to copyright for 50 years after publication: sections 11 and 23. However, the texts of laws, judicial opinions, and government reports are always free from copyright: section 3 (definition of literary work).
(All 50-year durations are computed from the beginning of the calendar year next following the year in which the work was first published or made. In other words, as of 2016, works published prior to 1 January 1966 are now in the public domain.)
This work might not be in the public domain outside Malaysia. The source, creator and year of publication are essential information and must be provided. See Wikipedia:Public domain and Wikipedia:Copyrights for more details.
