Using Hardcopy Documentation in the Transition to Online Documentation 
In the transition to online documentation, one of the communicator’s most effective tools can be a hardcopy document. Providing your users with a printed manual that introduces them to your product and your online documentation might be just the thing they need to get started using both. To create an effective hardcopy document, you must begin by gathering feedback, analyzing your audience, and setting your goals. You can then use that information to determine what to include, what to exclude, and what to call your hardcopy document.
