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:
“Those who have been once intoxicated with power, and have derived any kind of emolument from it, even though but for one year, never can willingly abandon it. They may be distressed in the midst of all their power; but they will never look to anything but power for their relief.”
—Edmund Burke (1729–1797)
“Reason, the prized reality, the Law, is apprehended, now and then, for a serene and profound moment, amidst the hubbub of cares and works which have no direct bearing on it;Mis then lost, for months or years, and again found, for an interval, to be lost again. If we compute it in time, we may, in fifty years, have half a dozen reasonable hours.”
—Ralph Waldo Emerson (1803–1882)
