You’d probably be surprised to learn that there is an international certifying organization of and for professional records and information managers http://www.icrm.org/about/ – clearly they work in the shadows at very large governmental and multinational organizations. Otherwise we’d have bumped into them more often.
For small companies the records management functions are typically outsourced to lawyers, accountants, bookkeepers and payroll services. However they are rarely described as records management services. By default bookkeepers typically end up with the lion’s share of the responsibilities, and many have little or no formal training.
