Every month, the University of Chicago press makes an eBook freely available to the intewebs for five days. This month, it is “You Were Never in Chicago” by Neil Steinberg. It is available for free until May 5th.
If you sign up on their web site, you will receive email notification on the first of each month, when they post a new book. I have never received any spam related to this service. I am in no way affiliated, blah blah blah. Haven’t even read this month’s book yet.
