Chicago Public Library had to curtail their hours as a cost cutting measure. That means that all branches are no longer open from 9 am to 9 pm. One some days the hours are 12n to 8 pm and others 10a - 6 pm. Hours are staggered so that nearby branches are open late on different days. This is a reasonable accommodation based on the need to trim the budget. Personally I visit the library in person mostly for recreational reading and videos. I visit rarely as I don't really think the branch is a pleasant place to visit. Chicago happens to have most of its population within 2 miles of one of their 79 branches. Each branch serves about 35,000 residents. This compares to the nearby suburbs of Skokie (population 63,000) with one location and Evanston (population 74,000) with a main library and two small branches. One county I did consulting for had one library in the entire county serving a geographic area much larger than the City of Chicago.
The library has a valuable resource that cost more than $10,000 year, but access is not easily available. Even if I were to go to branch my research time would be limited to the time they allow for their open computers. There is no priority for research as opposed to recreational or personal use. Probably most patrons have no need for JSTOR or any research level data base. I wonder how many times the reference librarians have ever used these data bases?
