Gun Digest Book of Concealed Carry by Mas Ayoob provides an excellent overview of many different concealed carry topics, with good pictures of various carry methods along with thorough discussions of each method's pros & cons. Strongly recommended.
The Concealed Handgun Manual by Chris Bird offers solid lessons woven in with engaging stories about how people defended themselves using handguns. Again, strongly recommended.
(Disclaimer: this one's mine.) The Cornered Cat: A Woman's Guide to Concealed Carry by Kathy Jackson gives a lot of practical info for female shooters, and a lot of general information including ethical, social, moral, and legal considerations of using deadly force that should be helpful for both men and women.
