Chicago, IL

Chicago Public LIbrary
Submitted by: Jean Petersen

  • We continued to stay open to the public during 2021, despite the many challenges of the Covid-19 pandemic.
  • As part of the continued restructuring of the Chicago Public Library Harold Washington Library Center, the Business/Science/Technology Unit was combined with Government Publications Department to become the Business/Science/Technology and Government Unit.
  • As a PTRC we continued to provide reference services to patrons through email, telephone, and socially distanced in-person interactions.
