Here's why:
* Copyright Duration: Copyright protection typically lasts for the life of the author plus 70 years. Shaw died in 1950, so his copyright expired in 2020.
* Public Domain: Works in the public domain are free for anyone to use, reproduce, and distribute without seeking permission or paying royalties.
However:
* Specific Editions: While the plays themselves are in the public domain, certain specific editions or adaptations might still be under copyright. For example, a modern translation or adaptation of Shaw's work may be protected by copyright.
* Performance Rights: Even though the plays are in the public domain, there may be performance rights organizations that regulate public performances. You might need to obtain a license from them for a public performance of Shaw's work.
To be safe:
* If you are unsure about the copyright status of a specific edition or adaptation, it's always best to check with the publisher or a copyright expert.
* If you are planning to perform a Shaw play publicly, it's essential to check with the relevant performance rights organization.
