A bulletin usually needs an institutional base. Local opportunity largely determines what this is. The spectrum ranges from a bulletin housed in a Health Ministry to a health insurance organization, a consumer organization, a professional association, a university department, or a non-governmental organization. Some bulletins have their own independent institutional base and are legally incorporated as a company or a non-profit organization. A bulletin housed within a parent organization needs a structure that allows the editors the freedom to do their job and to control editorial content. On the other hand, a parent organization can offer the advantage of taking responsibility for financial management and protecting the bulletin against legal threats. Chapter 11 discusses the pros and cons of different types of institutional and legal structures.
