Evangelical Christian Publishers Association
The Evangelical Christian Publishers Association (ECPA) is an international non-profit trade association whose member companies are involved in the publishing and distribution of Christian content worldwide. ECPA was cofounded by Hugh Revell Barbour and his brother Bill through a partnership with Christian publishers and has operated since 1974, with what the organization describes as a focus on "building networking, information, and advocacy opportunities within the industry".
