3. (75 ILCS 70/) Illinois Library Records Confidentiality Act.
(75 ILCS 70/1) (from Ch. 81, par. 1201)
Sec. 1. (a) The registration and circulation records of a library are confidential information. No person shall
publish or make any information contained in such records available to the public unless:
(1) required to do so under a court order; or
(2) the information is requested by a sworn law enforcement officer who represents that it is impractical to
secure a court order as a result of an emergency where the law enforcement officer has probable cause to
believe that there is an imminent danger of physical harm. The information requested must be limited to
identifying a suspect, witness, or victim of a crime. The information requested without a court order may
not include the disclosure of registration or circulation records that would indicate materials borrowed,
resources reviewed, or services used at the library. If requested to do so by the library, the requesting law
enforcement officer must sign a form acknowledging the receipt of the information. A library providing the
information may seek subsequent judicial review to assess compliance with this Section.
This subsection shall not alter any right to challenge the use or dissemination of patron information that is
otherwise permitted by law.
(b) This Section does not prevent a library from publishing or making available to the public reasonable
statistical reports regarding library registration and book circulation where those reports are presented so
that no individual is identified therein.
(b-5) Nothing in this Section shall be construed as a privacy violation or a breach of confidentiality if a library
provides information to a law enforcement officer under item (2) of subsection (a).
(c) For the purpose of this Section, (i) "library" means any public library or library of an educational, historical
or eleemosynary institution, organization or society; (ii) "registration records" includes any information a
library requires a person to provide in order for that person to become eligible to borrow books and other
materials and (iii) "circulation records" includes all information identifying the individual borrowing
particular books or materials.
