Textbook costs
Too many textbooks cost about as much as I pay for food each month. In some fields, teachers have few, if any, alternatives, but I don't think that's the case in the social sciences. A lot of useful outside materials are freely available online. For criminology I can assign, among many things, short DOJ reports and public radio audio clips.

This semester I've assigned two required books: Cry Rape: The True Story of One Woman’s Harrowing Quest for Justice and Cop in the Hood: My Year Policing Baltimore's Eastern District. Because Cry Rape is about a Madison case written by an area reporter, more than 30 copies are in the local libraries. Last semester, my students talked for around one hour about the book without my saying much, except to choose sometimes who would talk next. Besides the crime of rape, it covers the perspective of victims and police mistakes, such as tunnel-vision and overgeneralization. But I worried that my students got too negative of an angle on the police, so this semester I've also chosen Cop in the Hood, by a sociologist who joined the Baltimore police. Much of the book is his take on illegal drugs, so the book serves more than one purpose. Students must also pick from a list a third book to borrow from the library to learn about a topic that interests them.

When I taught research methods at UW-Madison, I was able to assign an older edition that the bookstore sold for $15-20. The small improvements in the newest edition were definitely not worth the more than $80. I got this idea from a UW professor, and I wish that others would try it so that books are used more while they still are in OK shape and students can save money. Online textbooks might be a relatively inexpensive path, but the main response to outrageous prices is for teachers to force textbook writers to use cheaper publishers or even create their own textbooks. If I'd had access to the Web in China, I could have edited my own casebook for contract law using public domain court opinions. Why more law professors don't do this disappoints me, especially given their enormous salaries.
