Many major book publishers wish to obtain audio rights in order to license them to an audio publisher. The split is generally 50% to the Publisher and 50% to the Author, and there are some special exceptions in the splits. If any agent retains these rights on behalf of the author (the agent’s client), the agent should attempt to sell these rights to an audio publisher. However, there are only a few literary agencies that have a person devoted to exclusively handle audio book rights for all their authors.
Unicorn for Writers will focus on these important rights, and either request a reversion of rights for unlicensed rights from a book publisher, check on the status of your existing audio licenses and check your audio rights royalty statements, contact your literary agent to get the ball moving on licensing these rights, and/or focus on selling these audio rights for you.
