SI 1995/3297, also known as “The Duration of Copyright and Rights in Performances Regulations 1995”, this UK law came into effect on January 1st 1996. At its most basic, it extended the copyright for any written work from 50 years after the author’s death, to 70 years. Any work which had already become public domain prior to 1st January 1996 remained public domain.
H. G. Wells died on the 13th August, 1946. All of his works thus missed becoming public domain in the UK by 225 days, and now remain copyright to his estate until 2016. Bizarrely, his works are public domain in the USA.
We’re currently investigating whether it is still feasible to publish War of the Worlds: Earth after learning of this curious quirk of legality.
