Learning About Document Management Guidelines

So lately I’ve been wondering about Document Management Guidelines.
Our content management system has grown unmanageable, so we need a better solution.
So I’ve been looking for information on Legal Document Management in order to find something the suits upstairs wil be willing to pay for.
Not the most exciting subject, of course, but I think it will save us a lot of money and time.
I’ll be looking forward to your comments.
