What are public records?

Public records are documents held by the government that members the general public has the right to access and view. They may exist as tangible paper copies of records held by in a government repository or as electronic records within an online database. 

Common types of public records include criminal records, court records, and vital records such as birth and death certificates. Public records can be accessed by the general public by making a public records request to the appropriate government agency.

Which federal law deals with public records in the United States? 

The Freedom of Information Act (FOIA) of 1967 is the major federal law regarding public records in the United States. The FOIA requires federal government agencies to release documents to the public when they make a records request, as long as the record in question doesn’t fall under one of nine exemptions outlined in the law. However, most people do not take advantage of the FOIA, and most record requests are made by businesses, law firms, and professionals.

Generally, if public records are to be used for a commercial purpose, the requester of the record must notify the agency of their intent while submitting the request.  

What are the Illinois laws governing public records?

The Freedom of Information Act/5ILCS 140 of the Illinois Compiled Statutes declares the right of members of the general public to inspect and copy records made by “public bodies”, which includes state and local governmental agencies, state universities and colleges, and boards, commissions, and bureaus of the state government. 

The IL FOIA defines the term “public records” to include “records, reports, forms, writings, letters, memoranda, books, papers, maps, photographs, microfilms, cards, tapes, recordings, electronic data processing records, electronic communications, recorded information and all other documentary materials pertaining to the transaction of public business”.

In Illinois, public records requests can be made in person or in writing, however, the Attorney General recommends that requests be made in writing due to the fact that time limits can not be set on in-person requests.
