The Collective voice of the Publishers. The Nigerian Publishers Association (NPA) is a professional association of publishers in Nigeria and the only collective voice of the publishers in Nigeria. It has been in existence since 1965. It is a rallying point for all book, journals, and electronic publishers in the country since its inception. The Association provides a forum through which publishers come together and deliberate on various issues affecting the publishing industry and the book trade at large. It is at the NPA that policies that would create an enabling environment and secure favourable trade terms both within Nigeria and overseas are made.
