I seem to write the same advice so often when I encounter organisations not using source control, that I thought I'd wrap up all my thoughts into one, pretty document that you can hand to your manager, technical lead, or whoever it is that you need to convince. This PDF (no registration required) is a short overview of the tools available, the benefits of source control in general, and some action points for actually making it happen. I am, of course, available for hire to help with source control implementation, but I hope the document also works on its own and is helpful.
