Adaptations and Derived Works
The enduring popularity of Sherlock Holmes has led to hundreds of works based on the character – both adaptations into other media and original stories. The copyright in all of Conan Doyle's works expired in the United Kingdom in 1980 and are public domain there. All works published in the United States prior to 1923 are in the public domain; this includes all Sherlock Holmes stories with the exception of some of the stories contained within The Case-Book of Sherlock Holmes. For works published after 1923 but before 1963, if the copyright was registered, its term lasts for 95 years. The Conan Doyle heirs registered the copyright to The Case Book (published in the USA after 1923) in 1981 through the Copyright Act of 1976.

Famous quotes containing the words derived and/or works:
“In the case of our main stock of well-worn predicates, I submit that the judgment of projectibility has derived from the habitual projection, rather than the habitual projection from the judgment of projectibility. The reason why only the right predicates happen so luckily to have become well entrenched is just that the well entrenched predicates have thereby become the right ones.”
—Nelson Goodman (b. 1906)
“In all Works of This, and of the Dramatic Kind, STORY, or AMUSEMENT, should be considered as little more than the Vehicle to the more necessary INSTRUCTION.”
—Samuel Richardson (1689–1761)
