§ 263. Reports. Every library or museum, other than a school library, which enjoys any exemption from taxation or receives state aid or other privilege not usually accorded to business corporations shall make the report required by section two hundred fifteen of this chapter, and such report shall relieve the institution from making any report now required by statute or charter to be made to the legislature or to any department, court or other authority of the state. These reports shall be summarized and transmitted to the legislature by the regents with the annual reports of the university.
