This paper aims to investigate the budget making process of public libraries. The focus is not on the library in isolation, but in relation to various forms of local government level. I interviewed seven library administrators in Saitama Prefecture about factors affecting the budget making process. On the basis of the data collected, I conclude that not only the administrator's negotiation ability and available human network resources affect the allocation of budgets, but also the council, the local administrative chief, the long-term plan, and the level of citizen support each play a significant role in this process.
