The final Sherlock Holmes stories by Sir Arthur Conan Doyle are entering the public domain in the US, along with other notable works such as the movie Metropolis and Virginia Woolf's To the Lighthouse. This means that anyone can republish, remix, or remake these works without needing permission from the rights holder. The public domain allows for new interpretations and adaptations of classic works, and can also help preserve and redistribute works that might otherwise be lost. The expiration of copyright on Sherlock Holmes marks the end of a long legal debate over the character's copyright status.
