(a) Each participating library shall receive state-supported services from a single regional library network. Geographical boundaries determine which regional library network a public library jurisdiction or institution, and its participating libraries, may join; exceptions may be made by the state board. Realignment of membership from one regional library network to another is permissible. A public library jurisdiction or an institution that is a member of a regional library network may also subscribe to services offered by other regional library networks. (b) Eligible libraries may receive state funds for services delivered under this chapter.
