This is the best bear book I have ever read - Bear attacks, their causes and avoidance by Stephen Herrero. Hurtig Publishers Edmonton/Toronto.
It is certainly worth a read for you outdoor types - camping/hunting/driving in bear country. I cannot understand the number of motorists who leave their cars and stand 20 yards from a grizzly to get a photo as I witnessed last summer near Jasper Alberta. Unbelievable.
