The online index seems to be incomplete. Licenses from 1920-1930 may not be there, for example. For license numbers to 1924, try searching Cook County, Illinois Marriage Indexes, 1912-1924 available on Ancestry.com. You can also search the Cook County, Illinois Marriage Index, 1930-1960 at Ancestry.com. This search allows you to use Soundex and to limit the results by day, month, and/or year. If you find index entries for licenses that aren't online, just mail in a request to the clerk's office (see link to form above).

Licenses are arranged by license number which means that they are in chronological order according to when they were issued. After 1893, Chicago and Cook County (outside the city) licenses are separate within each 100 numbers on the films. The Cook County licenses come first, followed by the Chicago licenses.

Information generally found on these records
Although the early Cook County marriage licenses do not provide parent names, they can provide valuable clues for further research. For example, many times a church name is given, or if not, a priest's or pastor's name can often be matched to a particular church for a particular time period using city directories.

About this Index
The Cook County Marriage Index for the years 1871-1899, is a series of handwritten registers with entries grouped by first letter of surname for each time period covered and arranged by license number (chronological) in ascending order. Groom indexes are available for the entire span; bride indexes are available from 21 November 1878 forward. Unlike the indexes after 1900, the groom indexes do not provide the name of the bride, and visa versa.
Why search this index?
If you can't locate the license using the online indexes, it might be worth trying to find a matching entry on the microfilm. If you do, you can use the license number to locate the marriage license on microfilms available through Family History Centers.
Information included in the index
(1) Because it's time-consuming to search these indexes, especially for common letters of the alphabet, it's useful to narrow the date before starting the search. Try searching the 1900 or 1910 censuses which asked the number of years a couple had been married or their ages at the time of the marriage or estimate the marriage date based on the birth of the first child.
(2) If you have a choice, search the alphabetic section that will have the fewest entries. In other words, if you have a choice between searching "S" in the groom index or "I" in the bride index, start with "I."
(3) The marriage index gives the date the license was issued, not necessarily the date the marriage occurred. For example, if a couple was married in January of 1888, the license could have been issued in December of 1887.
(4) If you don't find an entry in the groom index, it's probably worth checking the bride index, or visa versa.
(5) If you find an entry in a bride or groom index, it's possible to cross-check using the other index. In other words, if you are searching for a "John Smith" who married "Gertrude Miller" and find two "John Smiths" who married in 1898, it's possible to look in the bride index to see which license number was also issued to a "Gertrude Miller. This can save you time and money if you plan to order the license film.

(1) Some of the later indexes include entries for certificates that were issued up to 1919, and in one case up to 1936, however, it is very unlikely that you will have success in finding a marriage entry beyond 1916 in this index.
(2) For some years, the index is not strictly alphabetical and you will find names like "Schmidt" intermixed with "Schmid."
(3) If there is no date in the index, it's likely that the license wasn't returned to the county and that it will be missing on the license film. In those cases, it may be possible to get a copy of the marrige application from the Cook County Clerk's office. Information on the application may include the names of the bride and groom and a residential address, but it won't provide parent names.
(4) If you want to order a film at your local Family History Center in order to search the index, this list may be helpful in deciding which reel you would need.
