Nebraska Minimum Qualifications and Guidelines
"New York's minimum standards for public libraries are outlined in Commissioner's Regulations...and the authority for the State Education Department/State Library to create such minimum standards is in Education Law.
Our minimum standards do have significance, as a public library that does not meet them is not eligible for registration (licensing) and therefore, not eligible to receive local or state public funds."
