International Workers’ Day is May 1. American Libraries collects data about labor and libraries, including the number of library workers represented by the American Federation of State, County, and Municipal Employees; the size of the 2024 Mellon Foundation grant received by the University of California, Santa Cruz, library to establish an archive chronicling the life and work of labor activist Dolores Huerta, the number of oral histories from survivors of the 1911 Triangle Shirtwaist Factory Fire housed at the Kheel Center for Labor-Management Documentation and Archives at Cornell University in Ithaca, New York, and more.
