In the Handbook for Library Trustees of New York State, 2010 Edition found here, you will find under the heading of LIBRARY BOARD ORGANIZATION, the following:

Trustees of municipal, school district, and special district libraries, and trustees of cooperative library systems are required to file the oath of office specified in the State Constitution:

I do solemnly swear (or affirm) that I will support the Constitution of the United States, and the constitution of the State of New York, and that I will faithfully discharge the duties of the office of trustee of the _________ Library, according to the best of my ability.

The oath may be given by any officer of the court (judge, attorney, notary public) and must be filed in the local county clerk’s office. Failure to do so will vacate the position.

For more information, read “Oaths of Office – Is Your Board in Compliance with Public Officer’s Law?” by Bernard A. Margolis, State Librarian and Assistant Commissioner for Libraries, found in the Winter 2011 issue of Trustee.
