N.Y. Educ. Law § 252
The report of the state library to the legislature shall include a statement of the total number of volumes or pamphlets, the number added during the year, with a summary of operations and conditions, and any needed recommendation for safety or usefulness for each of the other libraries owned by the state, the custodian of which shall furnish such information or facilities for inspection as the regents may require for making this report. Each of these libraries shall be under the sole control now provided by law, but for the annual report of the total number of books owned by or bought each year by the state, it shall be considered as a branch of the state library and shall be entitled to any facilities for exchange of duplicates, inter-library loans or other privileges properly accorded to a branch.
