"Today, Authors Alliance releases Understanding Rights Reversion: When, Why, & How to Regain Copyright and Make Your Book More Available, a guide that arms authors with the information and strategies they need to revive their books. This guide is the product of extensive outreach to the publishing industry. In the process, we interviewed authors, publishers, and literary agents, ranging from a CEO of a major publishing house to contracts and rights managers of trade and academic presses, editorial assistants, novelists, and academic authors."
