The Legislature finds and declares that this chapter effects a state policy that each public library provide a minimum level of service, known as the foundation program, to the extent state funds are made available for that purpose as prescribed by this chapter. The Legislature, therefore, declares that state funds made available to each public library pursuant to this chapter, to the extent those funds are appropriations subject to limitation of a public library, shall be included in the appropriations limit of the state for purposes of Article XIIIB of the California Constitution. However, this chapter does not mandate any new program or higher level of service on any local government for which state funds are not made available as prescribed by this chapter.
