It is often said that collections of public library are too poor to meet user demands in terms of quantity as well as quality. It is also criticized that this situation is related to the lack of material budget and non-systematic purchasing process. Situated in such context, this study attempted to investigate current policies and regulations that control the material budget allocation and purchasing process in public libraries, because book purchasing process in public libraries is especially influenced by policies and regulations both in national and regional levels. Policies and regulations affecting material budget allocation and purchasing process were analyzed into 4 elements, namely about (1) financial foundation supporting collection development and material budget allocation, (2) the formation of material budget and discount rates, (3) prescribing characteristics of monographs public libraries purchase, and (4) acquisition process.
