For those of us without an MBA, www.cliffsnotes.com has a entire section on the history of management theory, how it came about, what the major schools are and where it is heading in the future.
There are also articles about organisational planning, HR, Structure, leadership and Total Quality Management
You can find the section here. And to top it all off, it's free and condensed. As a masters student these are fast becoming two of my favourite words :-)
