Section 4500.50 Standards for the Reproduction of Records by Microphotographic Processes with a View to the Disposal of the Original Records


a) Prior to the destruction of any original records, paper or documents, the agency head having such records in his custody under his supervision shall attach to each reproduction or continuous roll of reproductions, as the case may be, a certification as follows:


Certificate of Intent

(Letterhead of Certifying Officer)


This is to certify and declare that the microfilmed records which appear on this roll of film are accurate and true image of records of the (Describe Office), State of Illinois, and that such records are microfilmed in the ordinary course of business and are preserved by microphotography on this roll of microfilm, exactly as in the original.


We also certify that the original records on this roll are to be destroyed or disposed of in accordance with statutes, and only after inspection of the film has assured the accuracy and completeness of these records and their film images.


We also certify that the microphotography used to commit these documents and records to microfilm complies with requirements of the Local Records Commission of Cook County, Illinois for permanence of film images.





(Signature of Officer)





b) Preparation of the records for filming.

All documents in the file shall be microfilmed, unless their size or physical form prevents microfilming, in which case an explanation of their omission shall be microfilmed at the appropriate point on the roll.


c) Integrity of the original records.


1) The integrity of the original records shall be preserved on photographic or microfilm copies, so that such copies will be adequate substitutes for the original records in that they will serve the purposes for which such records were created or maintained and that such copies will contain all significant characteristics needed for probable future reference. A significant characteristic is any part of the record necessary for its interpretation including all words, numbers and illustrations.


2) Prior to microfilming, the original documents shall be so prepared, arranged, classified and indexed as to readily permit the subsequent location, examination and reproduction of the photographs thereof. Any significant characteristics of the records which would not reflect photographically (e.g., that the record is indistinct or that certain figures are of a color not suited to recording on microfilm) shall be noted by use of explanatory targets.


3) Each Film roll shall be identified by:


A) a title target showing the name of the office having custody of the records, a brief title of the record series, inclusive dates, file arrangement and the number of the approved applications authorizing the microfilming of the records.


B) a Certificate of Intent, title target information (as listed in Section 4500.50 (c) (3) (A)) and a "start file" target at the beginning of each reel of roll film.


C) an "end file" target and a Certificate of Authenticity placed at the end of each reel of roll film.


D) explanatory targets placed between the start file and end file targets as needed. Explanatory targets, show omissions, deletions, misfiles, retakes, and information required pursuant to Section 4500.50 (c) (2).


4) Each roll of original film or camera negative must be inspected after processing and before duplicate copies are made. The inspection must be conducted in such a manner as to reveal defects such as improper density, poor resolution, blurred or obscured images, improper document sequence, or improper identification targets. If a defect prohibits a clear, legible, hard copy print from the film, the original records must be re-photographed. The inspection must follow one of the following procedures:


A) randomly sampling the film, making sure that the samples include the beginning, middle, and end of the roll of microfilm. (It is suggested that this be done on all film as a minimum quality control.)


B) visually inspecting the film by passing each image through a reader and checking for overlapping, double or folded images, or other types of problems that would impair retrieving any information on the micro-images.


C) performing all subsection (B) as well as comparing the number of micro-images on the film with the number of documents that were to be microfilmed. (If the numbers coincide, the conclusion is made that every document has been microfilmed.)


D) individually comparing each document with each micro-image that was actually created. (This visual verification provides the highest assurance that every document has been properly filmed.)


5) If more than one percent of the original images need to be refilmed (approximately 30 images per roll), the entire roll must be refilmed.


6) The retake of documents be spliced to the end of the film along with a Certificate of Addition. The storage container must be labeled to reflect these additions.


7) At the end of each roll shall be a certificate worded as follows:


Certificate of Authenticity

(Service Company or Agency Letterhead)


This is to certify that the microfilmed images on this roll of microfilm starting with __________ and ending with __________ are true and accurate images of the documents of the ___________________________ (Describe Office.) These documents are microfilmed in the ordinary course of business as a part of the _________________________ (Service Company or Agency) procedures.



(Camera Operator)

(or Certifying Officer)


(Ill. Rev. Stat., 1985, ch. 116, par. 34.2)


8) When retaking of images is necessary, the following certificate shall be required.


Certificate of Additions

(Service Company or Agency Letterhead)


This is to certify that the microfilmed images appearing on this roll of film between Start Additions and End Additions are true and accurate images of those documents of the (Describe Office) which were missing or proved unreadable upon inspection of the original roll, and are to be spliced to such original roll for its completion.




(Camera Operator)

(or Certifying Officer)



9) No splice will be permitted between the start file and end file targets except for the court-ordered expungement of specific records. When such an order is issued, and deletions are made from the roll of film, a certification as follows must be inserted at the beginning of the reel of film.




This is to certify the deletion of microfilm images on this roll of microfilm occurred due to Court Order # _____________, dated_______________, signed by Judge ________________. No other images other than those listed in this order were deleted.




(Signature of Officer)





10) Each film carton shall be identified by a label or exterior marking showing:


A) roll number


B) name of office


C) title of record series


D) names of file units at the start of the roll, at space targets, and at the end of the roll.


E) the number of the application authorizing the microfilming of the record/record series.


11) Computer Output Microfilm (COM) is to be considered an original record and not a copy of an original record. Therefore, authentication requirements for source document microfilm, described in Section 4500.50 (c) (7), (8) and (9), do not apply to COM.


12) Microfiche and Aperture Cards


A) the microform must insure the integrity of the original record as required by Subsection (c)[1] and shall be inspected in the manner required by Subsection (c)[4].


B) the Certificate of Intent must appear at the beginning and the Certificate of Authenticity must appear at the end of each microfiche or aperture card. Explanatory targets showing omissions, deletions, misfiles, retakes and information required pursuant to Section 4500.50(C)(2) must be included where appropriate.


C) the headings on each fiche or aperture card must be legible without magnification, and must include the name of the office having custody of the records, a brief title of the record series, inclusive dates and approved application number.


D) any index registers or other finding aids must be microfilmed and located within the collection of filmed records.


13) Updateable Microfiche Systems

An agency considering using an updateable microfiche system should first contact the Local Records Unit of the Illinois State Archives to have the proposed application reviewed. The use of the updateable system will be approved if the updateable microfiche meets the following specifications.


A) each updateable microfiche must adhere to the standards specified in Section 4500.50(C)(12).


B) each time a microfiche is updated, either a Certificate of Authenticity must be inserted at the end of the added documents or an annotated reference to the Certificate of Authenticity must appear on each added image.


C) only records bearing retention periods of seven years or less may be placed on updateable microforms.


D) if a court ordered expungement is necessary, a Certificate of Deletion must appear at the place of the deleted image.


14) Prior to the destruction of records microfilmed under the authority of approved records schedules, the agency shall file with the Local Records Commission of Cook County a statement of compliance with its standards governing the microfilming of records. The statement shall include:


A) Name of agency having custody of the records


B) Date


C) Title and inclusive dates of the records series


D) The number of the list or schedule approved by the Local Records Commission of Cook County authorizing the project.


E) A statement as follows:


"I hereby certify that the film on which the records were reproduced complies with the standards given in Section 4500.60 of the rules of the Local Records Commission of Cook County".

F) Signature of the microfilm project supervisor or records custodian.


15) Master or Security Copy

The security or master microform shall not be used for reference purposes. Duplicates shall be used for reference and for further duplication on a recurring basis or for large-scale duplication, as for distribution of records on microforms. Agency procedures shall ensure that master microforms remain clean and undamaged during the duplication process. The agency may deposit a silver based film of permanent record materials in the Illinois State Archives, in roll form only.


16) Inspection

Security or Master films of permanent record microforms, and records microfilmed to dispose of the original record, shall be inspected every 2 years during their scheduled life. The inspection shall be made using a 1 percent randomly selected sample in the following categories: 70 percent microforms not previously tested, 20 percent microforms tested in the last inspection, and 10 percent control group. The control group shall represent samples of microforms from the oldest microforms filmed through the most current.
