Fredrik at corporateblogging.info has created a Corporate Blogging Primer, in which he has organized much of his sites content into a single PDF document that can be easily read and used for, well, whatvever you need it for. I think it's kind of funny to consense a blogging primer into a PDF file, but I can see the purpose in the corporate world - it's just not quite a dogfood thing to do is all. 
His definition of a corporate blog?
"A corporate blog is a blog published by or with the support of an organization to reach that organization's goals."
It's pretty well done. The contents include:

Six Types of Corporate Blogs

14 Steps to Your Business Blog

Of course, you should always check out other resources as well, like Robert's Corporate Weblog Manifesto for one, if you are thinking about blogging in the business world. Remember that a teeny-tiny bit of good, reasonable, simple forethought and planning can make blogging a very positive and useful thing for business.
