Welcome to the Online Library

The Online Library provides access to public datasets, from the NYC Comptroller’s Office, in accordance with Local Law 11 of 2012. The Open Data Plan was created with the goal of making the operation of the Comptroller’s Office more transparent, accessible and accountable to the public. Making data sets available online will allow the public to assist in the development of analyses, applications and other tools to improve City government and the lives of New Yorkers.
