I am writing music that uses three of his poems. How can I know if I can use them? Is there some type of Dylan Thomas legacy foundation that I can contact?
In most countries, copyright lasts for the life of the author plus a certain number of years, so all of an author’s works would fall into the public domain on the same date. In most countries, the “certain number of years” is 70. Dylan Thomas died in 1953, so his work is still in copyright. That means you need permission to use his poems.
