Spinoff Book Titles

In the course of putting together a display of Malcolm Gladwell "readalikes", I looked at the potential for a display of Freakonomics spinoffs.  Freakonomics is the assigned reading for all levels of AP English at Leon High this summer.  I concluded that, although Freakonomics inspired a number of "-onomics" imitators, there were not enough of them to furnish a two-week display.  But I did find this amusing article in the NYT from a year ago on how publishers try to capitalize on the titles of successful books:  Titlenomics, or Creating Bestsellers, by Patricia Cohen.
